Subject: 25.0.94; find: missing argument to `-exec'
Date: Tue, 12 Jul 2016 15:27:39 -0400

1. Install fish-shell (http://fishshell.com/) and use it as your default
shell, although it may be enough to launch emacs from inside fish.

2. emacs -Q

3. M-x rgrep RET

4. any string RET

5. any directory RET

Expected result:

grep is invoked on the given directory and files are returned.

Actual result:

find: missing argument to `-exec'

I believe this is because the fish shell interprets the "{}" as a brace
expansion -- see
http://fishshell.com/docs/current/index.html#expand-brace -- and needs
the braces to be escaped. Editing the grep command using C-u and
inserting quotes around the braces makes it work as expected.
