[bug-grep] [patch #3767] Remove two match_icase code paths from prline() in src/grep.c

[Charles Levert]

Follow-up Comment #1, patch #3767 (project grep):

Clarification:  for this to be no longer needed, the "grep-2.5.1-oi.patch"
patch from Red Hat must first be applied:
  :pserver:address@hidden:/cvs/dist
  devel/grep/grep-2.5.1-oi.patch
and
  <http://cvs.fedora.redhat.com/viewcvs/devel/grep/>.

Otherwise, should RE_ICASE not be available on all OSes, prline() is still
buggy as it stands so this patch #3767 eventually needs to be applied,
however another solution in src/search.c must first be found to emulate
RE_ICASE for OSes without it (if any).  On the other hand, maybe it's just
lib/regex.c that should be updated from a newer glibc versions and older OSes
can just rely on that ("./configure --with-included-regex").
