Don't try to apply format on merge commits #23
Description
Most our code is not formatted. We want to "get there" by steps, so we use this hook to format modified code and even then it is not always used.
When merge happens (I pull upstream changes to my topic branch), hook tries to format everything I pulled in the merge. If there is a lot of changes, format takes a lot of time. I would like it to just ignore merging commits. Even though formatting is right thing to do, merge commit is not a good time for it.
