Windows tortoiseSVN update to revision fails

It seems that the files variable isn't instanced at this point. Maybe moving lines 316 and 317 before line 311 would bring a sufficient fix ?

Here is the debug I'm getting in Sublime Text 3:

HypnotoadSVN: Update to revision
Traceback (most recent call last):
  File "C:\Program Files\Sublime Text 3\sublime_plugin.py", line 795, in run_

UnboundLocalError: local variable 'files' referenced before assignment

Thanks for the fix!
