Re: M-x grep not prepared for file names with spaces in them

[Dan Jacobson]

I'm so proud, 'twas my post that elicited a rare post from the RMS
himself, whereas the average leading brand post will not so elicit.
What? "on to the contents section, then" well, OK, I'll whip up some
"response contents".

[pssst, wouldn't "(2 matches found)' be of more service to the community?]

Ok boss, the pressure is on, here's what I came up with:

(setq grep-regexp-alist
;  '(("\\([a-zA-Z]?:?[^:( \t\n]+\\)[:( \t]+\\([0-9]+\\)[:) \t]" 1 2)))
   '(("\\([a-zA-Z]?:?[^:(\t\n]+\\)[:( \t]+\\([0-9]+\\)[:) \t]" 1 2)))
I took out the space here^  as seen on constant width char terminals

"Works great!"
Back in '92 I really understood regular expressions, but
now in '00 I'm like, sorry, what's "[a-zA-Z]?" going to match that
"[^:( \t\n]+" or "[^:(\t\n]+" won't?

Relax, it wasn't me, it was the grep output; but hey, if the pros call
it "GNU/Linux", count me in.
