People working in small teams sometimes forget to push their changes, causing general confusion. A gentle reminder in the command prompt should help.
Users migrating from centralised version control systems are especially likely to forget, so I've included git-svn support as a special case. Only SVN is supported because it's the only centralised version control system I have any experience with. The code is designed to make adding other version control systems easy for anyone that's interested.
