Discussed in
https://lists.gnu.org/archive/html/emacs-devel/2025-12/msg00903.html.
* lisp/progmodes/project.el (project-files) <vc>: Look up the
value of 'project-vc-ignores' inside DIR rather than project root.
This allows this variable to be applied in external dirs as well.
(project-ignores) <vc>: Do likewise.
(project--value-in-dir): Ensure that DIR has a trailing slash.
The caller might pass the value without slash if produced
differently.
* test/lisp/progmodes/project-tests.el
(project-vc-ignores-in-external-directory): New test.
(project-vc-supports-files-in-subdirectory): Update the test,
considering the subtle change in behavior: the directory DIR
directly includes a .dir-locals.el which sets project-vc-ignores,
which wasn't previously applied because it wasn't set in the root.
There are going to be new outstanding changes commands that will
deal in logs, not diffs.

In 2014, the Universal House of Justice announced modifications to
the Badí' calendar to bring it more in line with its original design.
>From 172 BE (Naw-Rúz 2015) onwards, Naw-Rúz is determined by the
vernal equinox as observed from Tehran, and the Twin Holy Birthdays
are calculated from the eighth new moon after Naw-Rúz.

description to mention the 2014 reform, Ayyám-i-Há, and the

astronomical calculations.
