[PATCH 0/7] grep: better support for binary files

["René Scharfe" <rene.scharfe@lsrfire.ath.cx>]

This series improves support of git grep for binary files.  It tries to
pick the low hanging fruits; at the end you can search _in_ files that
contain NUL characters, but you can't search _for_ NULs, yet.

[PATCH 1/7] grep: add test script for binary file handling

	This patch adds a simple test script documenting what git grep
	can do with binary files.

[PATCH 2/7] grep: refactor handling of binary mode options
[PATCH 3/7] grep: --count over binary

	These two makes git grep handle counting in binary files like
	GNU grep does.

[PATCH 4/7] grep: use memmem() for fixed string search
[PATCH 5/7] grep: continue case insensitive fixed string search after NUL chars

	These two patches make git grep -F work on binary files.

[PATCH 6/7] grep: add regmatch(), a wrapper for REG_STARTEND handling
[PATCH 7/7] grep: use regmatch() for line matching

	The final patches make git grep work on binary files if the
	platform's regexec() supports the flag REG_STARTEND.  Our own
	version in compat/ doesn't, unfortunately.
