annotate common.cpp @ 74:10eb97683aa9

* Show branch names even for changes with children, if those children are on a different branch
* Pick up remote repo path from local repo via hg paths
* Some work towards breaking down files into various groups based on status
* Add /usr/local/bin to path for hg (temporary hack I hope)
