Subject: 24.0.50; rgrep breaks when called programmatically
Date: Thu, 1 Dec 2011 11:08:07 -0800

Evaluating (rgrep "hello") results in "/bin/bash: hello: command not found"

The docstring for rgrep claims that its first argument is intended to be
a regexp, but clearly it's attempting to execute it via bash.
