; (grep-read-files): Fix completion table

* lisp/progmodes/grep.el (grep-read-files): Cease returning
some completion candidates unconditionally.  Use
'completion-file-name-table' over 'read-file-name-internal'
because the latter uses 'completion-table-with-quoting', and
that doesn't blend well with other tables in
'completion-table-merge'.
