Template for commit message
It would be nice to be able to set a default/template commit message in thg. With a template message it will result in less errors when adding an issue number to a commit message.
So for example the template might be:
I realize there is already functionality to enforce using an issue # in the commit message - but there may be cases where there is no issue # for the commit - so the committer could just remove the issue # from the message in that case.
Also, this should probably be configurable per repository and apply to everybody who uses the repository - much like the .hgignore file.
