(tramp-backtrace): New defun.
(tramp-handle-insert-file-contents): Use `visit' when inserting
the local copy.
* net/tramp-sh.el (tramp-sh-handle-set-visited-file-modtime): Use
`remote-file-name-inhibit-cache'.
* fileio.c (Fwrite_region): Don't use the heuristic on empty files,
as FAT32 doesn't update time stamps when truncating them.
Also, check that a file time stamp is not a multiple of 100 ns;
this should catch all instances of the problem on MS-Windows,
as its native file system resolution is 100 ns or worse, and
checking for a non-multiple of 100 ns should impose only a small
overhead on systems with ns resolution.

src/w32.c (normalize_filename): Accept an additional argument
MULTIBYTE; if non-zero, traverse the file name by bytes and don't
downcase it even if w32-downcase-file-names is non-nil.
(dostounix_filename): Accept an additional argument MULTIBYTE and
pass it to normalize_filename.
(emacs_root_dir): Adjust.
src/msdos.h (dostounix_filename): Adjust prototype.
src/w32.h (dostounix_filename): Adjust prototype.
src/msdos.c (dostounix_filename): Accept an additional argument and
ignore it.
(init_environment): Adjust callers of dostounix_filename.
src/fileio.c (Ffile_name_directory, file_name_as_directory)
(directory_file_name, Fexpand_file_name)
(Fsubstitute_in_file_name): [DOS_NT] Adjust call to
dostounix_filename.
[WINDOWSNT]: Downcase file names if w32-downcase-file-names is
non-nil.
(Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
variables, as egetenv is case-insensitive for DOS_NT.
src/dired.c (file_name_completion): Don't call Fdirectory_file_name
with an encoded file name.
src/w32proc.c (Fw32_short_file_name, Fw32_long_file_name): Adjust
calls to dostounix_filename.
src/w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.

src/emacs.c (decode_env_path) [DOS_NT]: Adjust call to
dostounix_filename.
src/callproc.c (Fcall_process) [MSDOS]: Adjust call to
dostounix_filename.
variables deeper to the loop that searches for the next match.
Add bindings for `isearch-nonincremental' and `isearch-adjusted'.
Use `isearch-search-fun-default' instead of `isearch-search-fun'.
* lisp/isearch.el (isearch-search-fun-default): Check for null
first element of isearch-cmds as a precaution when it's used
with inactive isearch.
Fixes: debbugs:13579
* fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
the file's time stamp doesn't change if Emacs happens to write nothing
to the file, and on a buggy file system this could cause Emacs to
incorrectly infer that the file system doesn't have the bug.
Avoid this problem by inhibiting the inference in this case.
Fixes: debbugs:13149
src/callproc.c (Fcall_process): Make sure program name in PATH and
new_argv[0] is encoded, if needed. Otherwise, un-encoded string
is passed to exec/spawnve, which fails unless the file-name
encoding is UTF-8.
On my host, this speeds up directory-files-and-attributes by a
factor of 3, when applied to Emacs's src directory.
These functions are standardized by POSIX and are common these
days; fall back on a (slower) gnulib implementation if the host
is too old to supply them.
* .bzrignore: Add lib/dirent.h.
* lib/Makefile.am (libgnu_a_SOURCES): Add openat-die.c, save-cwd.c.
* lib/careadlinkat.c, lib/careadlinkat.h: Merge from gnulib,
incorporating: 2013-01-29 careadlinkat: do not provide careadlinkatcwd.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* lib/dirent.in.h, lib/fdopendir.c, lib/fstatat.c, lib/openat-priv.h:
* lib/openat-proc.c, lib/openat.h, m4/dirent_h.m4, m4/fdopendir.m4:
* m4/fstatat.m4: New files, from gnulib.
* lib/openat-die.c, lib/save-cwd.c, lib/save-cwd.h: New files.
These last three are specific to Emacs and are not copied from gnulib.
They are simpler than the gnulib versions and are tuned for Emacs.
* admin/merge-gnulib (GNULIB_MODULES): Add fdopendir, fstatat, readlinkat.
(GNULIB_TOOL_FLAGS): Do not avoid at-internal, openat-h.
Avoid dup, open, opendir.
* nt/inc/sys/stat.h (fstatat):
* nt/inc/unistd.h (readlinkat): New decls.
* src/conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
* src/dired.c: Include <fcntl.h>.
(open_directory): New function, which uses open and fdopendir
rather than opendir. DOS_NT platforms still use opendir, though.
(directory_files_internal, file_name_completion): Use it.
(file_attributes): New function, with most of the old Ffile_attributes.
(directory_files_internal, Ffile_attributes): Use it.
(file_attributes, file_name_completion_stat): First arg is now fd,
not dir name. All uses changed. Use fstatat rather than lstat +
stat.
(file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
* src/fileio.c: Include <allocator.h>, <careadlinkat.h>.
(emacs_readlinkat): New function, with much of the old
Ffile_symlink_p, but with an fd argument for speed.
It uses readlinkat rather than careadlinkatcwd, so that it
need not assume the working directory.
(Ffile_symlink_p): Use it.
* src/filelock.c (current_lock_owner): Use emacs_readlinkat
rather than emacs_readlink.
* src/lisp.h (emacs_readlinkat): New decl.
(READLINK_BUFSIZE, emacs_readlink): Remove.
* src/sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
(emacs_norealloc_allocator, emacs_readlink): Remove.
This stuff is moved to fileio.c.
* src/w32.c (fstatat, readlinkat): New functions.
(careadlinkat): Don't check that fd == AT_FDCWD.
(careadlinkatcwd): Remove; no longer needed.

* make-dist: Only README files exist in lisp/ now, not README*.
* doc/misc/calc.texi (Help Commands): Mention etc/CALC-NEWS.
* etc/CALC-NEWS: Move here from lisp/calc/README, README.prev.
* lisp/calc/README, lisp/calc/README.prev: Rename/merge to etc/CALC-NEWS.
`string-as-unibyte'. The function does not exist on XEmacs, and
likely we need another approach.
* net/tramp-sh.el (tramp-compute-multi-hops): Check, whether
`tramp-gw-*' variables are bound.
* lisp/files.el (basic-save-buffer-2):
Choose coding system for writing the file before backing it up.
* src/fileio.c (choose_write_coding_system): Make it callable from Lisp.
(Fwrite_region): If coding-system-for-write is set, don't call
choose_write_coding_system.
Move the last piece of choose_write_coding_system here.
(syms_of_fileio): Add choose-write-coding-system.

(opascal-newline-always-indents): Remove custom.
(opascal-tab, opascal-newline): Remove commands.
(opascal-new-comment-line): Insert "\n" instead of calling newline.
(opascal-mode-map): Keep default bindings for RET and TAB and DEL.
(opascal-save-match-data): Remove, use save-match-data instead.
(opascal-save-state): Use with-silent-modifications.
