When I run git cl diff, I see the following:

$ g cl diff                                                                                                 [±test_internal_changes_cl ✓▴]
Traceback (most recent call last):
  File "/usr/local/google/home/martiniss/depot_tools/git_cl.py", line 4626, in <module>
    sys.exit(main(sys.argv[1:]))
  File "/usr/local/google/home/martiniss/depot_tools/git_cl.py", line 4608, in main
    return dispatcher.execute(OptionParser(), argv)
  File "/usr/local/google/home/martiniss/depot_tools/subcommand.py", line 252, in execute
    return command(parser, args[1:])
  File "/usr/local/google/home/martiniss/depot_tools/git_cl.py", line 4320, in CMDdiff
    rtn = cl.CMDPatchIssue(issue, reject=False, nocommit=False, directory=None)
  File "/usr/local/google/home/martiniss/depot_tools/git_cl.py", line 1300, in CMDPatchIssue
    if issue_arg.isdigit():
AttributeError: 'int' object has no attribute 'isdigit'


This is only for branches with an issue associated with it.
