bug#14900: 24.2; no recursion support for directory-files

[address@hidden]

Perhaps this is more of a missing feature report.

If i want to tell emacs to recurse from '.', and open every file that matches
a certain pattern (a la `find`), i need to use a gnus function. See this code
suggestion from 'jlf' in #emacs:

(remove-if-not (lambda (file) (string-match some-regexp file))
               (gnus-recursive-directory-files default-directory) )

It surprized me that i'd have to have a huge pkg like gnus loaded to do
something like this.

thanks,
Eric
