[BUG] git grep broken on master - won't work when merging

[BUG] git grep broken on master - won't work when merging

[Martin Langhoff]

Strange behaviour of git grep on one of the projects I hack on...

  $ git --version
  git version 1.5.3.5.561.g140d

  $ git grep LOB lib
  fatal: insanely many options to grep

After a bit of head-scratching I realised I was in the middle of a
merge, with some unresolved paths in the lib directory. A bit of
testing shows that the unresolved index is probably the problem:

  $ git grep LOB lib
  fatal: insanely many options to grep

  # an unresolved file
  $ git grep  LOB lib/accesslib.php
  fatal: insanely many options to grep


  $ git grep --cached LOB lib
  (... expected grep output...)

  $ git reset --hard
  $ git grep LOB lib
  (... expected grep output...)

... not sure what the correct behaviour should be -- I guess the most
reasonable action would be to grep the files on disk for those
unresolved paths. In any case, the error message is insanely many
confusing to user! ;-)

Probably whitespace damaged...

I think 36f2587ffb6802cb38071510810f48cddfc4f34a (grep: do not
skip unmerged entries when grepping in the working tree.) is the
dud one.  Would this help?
