Recentf and gzipped elisp source files

[Stephen Berman]

Since the change by which Emacs lisp source files are automatically
gzipped if possible, these are not listed in the recentf menu under
the entry "emacs-lisp" when recentf-menu-filter is set to
recentf-arrange-by-mode, although such files are visited in
emacs-lisp-mode; rather, they are listed under the entry "others".  A
possible fix is to add ("\\.el.gz" . emacs-lisp-mode) to
auto-mode-alist, but I don't know if this would have undesirable
consequences elsewhere.
