[PATCH 00/20] git-p4: Various code tidy-ups

This patch set contains multiple patches to improve consistency and tidyness of the git-p4 script's code style.

Many of these patches have been driven by the guidlines contained in the Python PEP8 "Style Guide for Python Code" and were applied using a mixture of human intervention, and tools including autopep8 and pycodestyle.

This patch-set stops short of bringing git-p4 into full PEP8 compliance, most notably in regard to the following items:

  - There is no patch to apply the recommended column limit of
    79-characters,
  - There is no patch to correct hanging indents of multi-line
    declarations such as multi-line function delcarations, function
    invocations, etc.

Patches to correct these items may be provided later.
