... There are other little things, like not being able to trim the check-in filelist when editing the check-in message. For example, say you have 10 files checked out scattered around the Python source tree and you want to check 9 of those in.
This seems dubious, since you're not checking in the state you actually have locally, and you were careful to run the full Python test suite with your full local state ;-)
Currently with svn you have to manually specify those 9 to be sure to not include the remaining one. With p4 you just say to check-in the whole tree and then remove that one from the list give you in your editor with entering the check-in message. Not that big of a deal.
As a purely theoretical exercise <wink>, the last time I faced that under SVN, I opened the single file I didn't want to check-in in my editor, did "svn revert" on it from the cmdline, checked in the whole tree, and then hit the editor's "save" button. This doesn't scale well to skipping 25 of 50, but it's effective enough for 1 or 2.
