emacs-27 7a12ab5: Fix project.el commands in "transient" projects

[Eli Zaretskii]

branch: emacs-27
commit 7a12ab5ea2257f8e9d3f4ba03918cf9709a728e1
Author: Eli Zaretskii <address@hidden>
Commit: Eli Zaretskii <address@hidden>

    Fix project.el commands in "transient" projects
    
    * lisp/progmodes/project.el (project--files-in-directory): Run
    local DIR directory names through 'expand-file-name', so that "~/"
    is expanded, in case the shell doesn't or the shell's notion of
    the home directory is different from that of Emacs.  (Bug#40940)
