Summary: Previously we relied on the list of files created by strip to decide what directories to strip. It turns out this list wasn't adequate though, since it's possible for directories to change even when files do not. For example, during a merge if different files were added on different sides of the merge, the files don't change during the merge but their containing directory does. This diff special cases merge commits to make sure all the directories affected by the merge are included in the strip.
