Junio C Hamano	d99ebf0817	Split grep arguments in a way that does not requires to add /dev/null. In order to (almost) always show the name of the file without relying on "-H" option of GNU grep, we used to add /dev/null to the argument list unless we are doing -l or -L. This caused "/dev/null:0" to show up when -c is given in the output. It is not enough to add -c to the set of options we do not pass /dev/null for. When we have too many files, we invoke grep multiple times and we need to avoid giving a widow filename to the last invocation -- otherwise we will not see the name. This keeps two filenames when the argv[] buffer is about to overflow and we have not finished iterating over the index, so that the last round will always have at least two paths to work with (and not require /dev/null). An obvious and the only exception is when there is only 1 file that is given to the underlying grep, and in that case we avoid passing /dev/null and let the external "grep -c" report only the number of matches.

Split grep arguments in a way that does not requires to add /dev/null.

In order to (almost) always show the name of the file without
relying on "-H" option of GNU grep, we used to add /dev/null to
the argument list unless we are doing -l or -L.  This caused
"/dev/null:0" to show up when -c is given in the output.

It is not enough to add -c to the set of options we do not pass
/dev/null for.  When we have too many files, we invoke grep
multiple times and we need to avoid giving a widow filename to
the last invocation -- otherwise we will not see the name.

This keeps two filenames when the argv[] buffer is about to
overflow and we have not finished iterating over the index, so
that the last round will always have at least two paths to work
with (and not require /dev/null).

An obvious and the only exception is when there is only 1 file
that is given to the underlying grep, and in that case we avoid
passing /dev/null and let the external "grep -c" report only the
number of matches.

git-grep: show pathnames relative to the current directory

By default, the command shows pathnames relative to the current
directory.  Use --full-name (the same flag to do so in ls-files)
if you want to see the full pathname relative to the project root.

This makes it very pleasant to run in Emacs compilation (or
"grep-find") buffer.

Fix "grep -w"

We used to find the first match of the pattern and then if the
match is not for the entire word, declared that the whole line
does not match.

But that is wrong.  The command "git grep -w -e mmap" should
find that a line "foo_mmap bar mmap baz" matches, by tring the
second instance of pattern "mmap" on the same line.

Problems an earlier round of "fix" had were pointed out by Morten
Welinder, which have been incorporated in the t7002 tests.
