+ * Handle operating in sub-trees of a git repository.
+ When looking for git commits that affect the wiki, only include changes
+ that affect the ikiwiki source directory. If that is not the top-level
+ directory in this git repository, strip off the prefix as given by
+ `git-rev-parse --show-prefix` from all names reported by git-log.
