Hi Daniel,
I use
(setq igrep-options "-Pi")
and
(setq grep-command "grep -Pni ")
which gives me multi-line match capability with
grep (GNU grep) 2.5
under
CYGWIN_NT-5.1 D5DC120J 1.5.7(0.109/3/2) 2004-01-30 19:32 i686 unknown unknown Cygwin
in
XEmacs 21.5 (beta17) "chayote" (+CVS-20040611) [Lucid] (i586-pc-win32, Mule) of Sat Jun 12 2004 on D5DC120J
I guess if I had no grep, but only perl, your script could be useful.
