* lisp/progmodes/python.el
(python-shell-completion-native-get-completions): Match dummy output
even when readline is configured in non-default ways. (Bug#51010)

* lisp/vc/vc.el (vc-diff-internal): Fix diff mode being set before

* src/nsterm.m (ns_compute_glyph_string_overhangs): When the first
glyph of a glyph string is a composite glyph, `s->nchars' is 0, so
"s->char2b + s->nchars - 1" dereferenced a position before buffer
`s->char2b'. Instead, rewrite part of the function to distinguish
between character glyphs and composite glyphs. For character glyphs,
calculate the font metrics using the `text_extents' function, passing
it the entire glyph string; for composite glyphs, call
`composition_gstring_width'. (Bug#51105)
