Subject: 28.2; rgrep issue when called through C-x C-e
--text follows this line--

Hello,

To reproduce the issue:
 1. Paste this code in the *scratch* buffer : (rgrep "foo" "*.org" "~"
 nil)
 2. Execute it through C-x C-e

I get a backtrace with : 'Debugger entered--Lisp error:
(wrong-type-argument stringp nil)'.

If I call 'rgrep' interactively through `M-x rgrep'. Not only, it works
but it also make subsquent calls to grep through C-x C-e work.

Thank you for your support.
