When a file is committed to a branch, the branch name should be provided to the server side scripts.  Ideally, the branch name could be passed in via an argument in commitinfo, loginfo, editinfo, etc.

For example:

I would like to be able to restrict commits to a particular branch of a particular module.  I can write a script to handle the logic, but this script needs to know the name of the branch for which the commit is made.  Ideally, I would like to add the following line to commitinfo where %{b} represents the branch name:

module1    $CVSROOT/CVSROOT/commitcheck %{b}

${b} should expand to the actual branch name or "NONE" if this change is not being made to a branch.

Similarly, this feature would be useful for verifying commit messages (editinfo) only on a particular branch or modifying recipient lists (loginfo) based on a particular branch (this issue is non-blocking for the loginfo case since the cvs notification actually contains the branch name).
