M-j did not work. Also I do not think that that is how that function
was supposed to behave. Looking into the fille grep.el there is a
list called "grep-files-aliases" I think that is the list that should be
fed to the completion instead of whatever is generated by
read-file-name-internal.
One could even build a better list of file extensions
because asking for "matching wildcards" and providing files
instead of file extensions does not quite make sense to a user.
