[PATCH 0/5] grep: remove redundant code & reflags from API

Here's a follow-up to a small tangent of discussion in my ~30 patch
grep cleanup series.

There are no functional changes here, just getting rid of dead code,
and removing the POSIX `regflags` variable from the grep API used by
grep/log, which was the cause of the long-standing bug of "-i" not
working with PCRE when used via git-log.

Ævar Arnfjörð Bjarmason (5):
  grep: remove redundant double assignment to 0
  grep: remove redundant grep pattern type assignment
  grep: remove redundant "fixed" field re-assignment to 0
  grep: remove redundant and verbose re-assignments to 0
  grep: remove regflags from the public grep_opt API
