Follow-up Comment #2, bug #35410 (project make):
Oops, yes, I'm agree.
Another possible (and quite simple to apply it right now) optimization is to
use something like:
pat->length = len/2 + strlen(pat->str + len/2)
It seems to be safe as far as the string can't become shorter than a half of
the original one (the worst case is like '\%' -> '%').
The patch for the latest version from CVS is attached below. It also changes
the way of checking whether the called function is "filter" or "filter-out".
(file #25259)
