Teach mergetool to pass "-O<orderfile>" down to `git diff` when
specified on the command-line.
Signed-off-by: David Aguilar <davvid@xxxxxxxxx>
---
This is a replacement patch for 4/4 from the original series.
The changes are stylistic -- the "order_file" variable name and
"-O<order-file>" in the usage were changed to "orderfile" and
"-O<orderfile>" for consistency with the documentation.

-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`.
