matches things properly using Perl 5.8 in for example
src/bin/initdb/Makefile (matches a total of around 10 Makefiles), but
in 5.10 it simply does not match anything...
Any perl guru out there who can comment on why? ;-)
The answer is actually simple, the \n needs the multiline modifier,
and thus the m needs to be part of the quote-like operator.
The perl doc states:
"This operator quotes (and possibly compiles) its STRING"
(it seems 5.8 did not compile, but 5.10 does)
I feel that it is rather not a perl bug, and that the modifiers need to
be put
on the qr{}. I do not quite see why this re needs to be multiline in the
first place,
but I have not touched that in the attached patch, that is ready to
apply.
(modification works in perl 5.6, 5.8, 5.10)
Thanks, that makes sense. I wonder how it ever worked before. Anyway,
patch applied back as far as 8.2.
cheers
