Now that we have a regex engine that supports REG_STARTEND this test
should fail if "git grep" can't grep NULL characters.
Platforms that don't have a POSIX regex engine which supports
REG_STARTEND should always define NO_REGEX=YesPlease when compiling.

Search patterns in a file specified with -f can contain NUL characters.
The current code ignores all characters on a line after a NUL.
Pass the actual length of the line all the way from the pattern file to
fixmatch() and use it for case-sensitive fixed string matching.

Refactor REG_STARTEND handling inlook_ahead() into a new helper,
regmatch(), and use it for line matching, too. This allows regex
matching beyond NUL characters if regexec() supports the flag. NUL
characters themselves are not matched in any way, though.

Functions for C strings, like strcasestr(), can't see beyond NUL
characters. Check if there is such an obstacle on the line and try
again behind it.

Allow searching beyond NUL characters by using memmem() instead of
strstr().

As with the option -c/--count, git grep with the option -l/--name-only
should work the same with binary files as with text files because
there is no danger of messing up the terminal with control characters
from the contents of matching files. GNU grep does the same.
Move the check for ->name_only before the one for binary_match_only,
thus making the latter irrelevant for git grep -l.

The intent of showing the message "Binary file xyz matches" for
binary files is to avoid annoying users by potentially messing up
their terminals by printing control characters. In --count mode,
this precaution isn't necessary.
Display counts of matches if -c/--count was specified, even if -a
was not given. GNU grep does the same.
Moving the check for ->count before the code for handling binary
file also avoids printing context lines if --count and -[ABC] were
used together, so we can remove the part of the comment that
mentions this behaviour. Again, GNU grep does the same.
