Teach mergetool to pass "-O<orderfile>" down to `git diff` when
specified on the command-line.

Changes since v2:
The tests no longer rely on "grep -A" and instead use "git grep"
for portability. The mergetool output in the test is redirected
to a file so that we can catch its exit code.
The $orderfile variable is now passed using ${xxx:+"$xxx"}
to avoid conditional logic.

-DIFF ORDER FILES
-----------------
-`git mergetool` honors the `diff.orderFile` configuration variable
-used by `git diff`. See linkgit:git-config[1] for more details.
+-O<orderfile>::
+ Process files in the order specified in the
+ <orderfile>, which has one shell glob pattern per line.
+ This overrides the `diff.orderFile` configuration variable
+ (see linkgit:git-config[1]). To cancel `diff.orderFile`,
+ use `-O/dev/null`.
