    Tweak c-mode bug reporting address
    
    * lisp/progmodes/cc-mode.el (c-mode-help-address):
    Switch to bug-gnu-emacs.  This is an alias for the previous
    submit@debbugs address, except that if no Package header can be found,
    as often seems to happen for cc-mode reports, debbugs will assign
    the report to the "emacs" package rather than to "debbugs.gnu.org".

    Fix find invocation for macOS (Bug#48471).
    
    * lisp/progmodes/project.el (project--files-in-directory): Instead of
    appending a slash (which doesn't work well with macOS find), remove
    trailing slash and pass -H instead.
