pull: avoid referencing a variable before it is initialized If `urlutil.get_pull_paths()` somehow yields nothing, the reference after the loop appears to be a problem. I noticed this because PyCharm flagged (and still flags) the initialization of this inside the loop as somehow unused. I'm not sure why 1 isn't returned directly where it is set to the result of `postincoming()`, but maybe the code is structured this way in anticipation of future work.
