rgrep forces me to choose a directory, e.g.,
(rgrep "INIT" "* .*" "/usr/share/initscripts/" nil)
when I really want to choose a wildcard of several directories.

OK, so I use repeat-complex-command to forge in
(rgrep "INIT" "* .*" "/usr/share/init*" nil)
And low and behold, rgrep assumes it can cd to that "directory" and
proceeds even though the cd failed! So at least it should check that its
cd doesn't fail, even if wildcard directories will never be implemented.

In GNU Emacs 23.1.91.1

This seems to be on purpose:

    (unless (and dir (file-accessible-directory-p dir))
      (setq dir default-directory))

If you name a directory and it doesn't exist, then default-directory is
used, and it's done on purpose:

commit 32a2cf25a74160b855041c176d2e7e937baa4de8
Author: Juri Linkov <juri <at> jurta.org>

    (lgrep, rgrep): At the beginning
    set `dir' to `default-directory' unless `dir' is a non-nil
    readable directory.  (Bug#4052)
    (lgrep, rgrep): Change a weird way to report an error
    from using `read-string' to using `error'.
    Instead of using interactive arguments in the function body,
    add new argument `confirm'.

So I'm closing this bug report.
