The quotes are not part of the regex, and are only necessary
when running the command via a shell (`M-x grep' uses
start-process-shell-command).
The correct way to use call-process would be:
(call-process "grep" nil BUFFER nil "epsilon\\($\\)" "foo")
Uh, isn't that what I wrote(?):
(call-process "grep" nil
(generate-new-buffer "Result")
nil "epsilon\\($\\)" "foo")
This does *not* work for me. That's the point - that is the code I started
with. It works if I change \\($\\) to $ (but that's not what I need in the
general case).
(And yes, I realize that the quotes are not part of the regexp. By "I showed
the regexp with double-quotes" I meant that I showed it enclosed in
double-quotes.)
