[TxMt] env variable to get all project files?

I vaguely recall this question coming up but I wanted to re-emphasize it. There is currently no way for a command to operate on all files contained in a project [or is there?]. there is TM_PROJECT_DIRECTORY but this is only a path to where <project>.tmbundle lives. Allan do you have plans for adding this soon?

Some motivations for such a request : Another developer and I would like to work on some eclipse-style refactoring tools [ http://www-128.ibm.com/developerworks/library/os-ecref/ ] but there would have to be a way to access all files in a project. Also, the one reason holding me back from using the Subversion bundle [almost] exclusively is its inability to commit all files in a project.
