Make --stdin option to "log" family read also pathspecs
Similar to the command line arguments, after giving zero or more revs, you can feed a line "--" and then feed pathspecs one at a time. With this ( echo ^maint echo -- echo Documentation ) | git log --stat --oneline --stdin master -- t lists commits that touch Documentation/ or t/ between maint and master.
