Re: grep --no-index and pathspec

Hi everyone,

I encountered some strange behaviour with grep when using both the  
--no-index option and a pathspec. Glob patterns seem to be ignored:

----------
$ git grep -l --no-index . -- '*.bib'
paper.bib
paper.tex
ex1.tex
----------

But on the other hands, leading path matches work:
----------
$ git grep -l --no-index . -- 'paper'
paper.bib
paper.tex
----------

Without the --no-index option, everything works fine:
----------
$ git grep -l --no-index . -- '*.bib'
paper.bib
----------

This is with git version 1.7.4, but I encountered it also with the  
1.7.2.3 Debian package.

"grep --no-index" and "grep" have different codepaths for looking up the
files/blobs. If I read that correctly then "grep --no-index -- pathspec"
only does a literal match at the left boundary, whereas for the normal
mode glob patterns are allowed.

CC'ing Junio who created "--no-index".
