diff-merges: rename "combined_imply_patch" to "merges_imply_patch"

This is refactoring change in preparation for the next commit that
will let -m imply -p.

The old name doesn't match the intention to let not only -c/-cc imply
-p, but also -m, that is not a "combined" format, so we rename the
flag accordingly.
