I think this would work fine.  Darcs can check that the patch applies
cleanly, so it could pretty easily be made "safe".  The tests and stuff
would all be fine, since they are done after the set of changes is

Another possibility (which wouldn't interact so well with gui tools) would
be to allow the user to pop up a text editor on the files while selecting
changes, with the text editor opening up a temporary copy of the file, so
your changes would go into the recorded patch, but not modify the working
