histedit: drop unnecessary check for "self.node is not None" We are doing hex(self.node) just a few lines up, so it shouldn't be None. The only way it could be none is if it was reassigned in between. The only way that can happen is if the user had put a "ffff..." wdirhex revision in the histedit script. This code is much older than the "ffff..." identifier, so I'm confident it's not there to handle that case. I'll let someone else add proper checks for "ffff..." if they care enough.

context: extract partial nodeid lookup method to scmutil We will add another caller soon, and there's a non-obvious reason to use the unfiltered repo that we don't want to copy across the code base. Differential Revision: https://phab.mercurial-scm.org/D3189
