repo: Cleaned up pylint/pep8 violations

I noticed when running pylint (as the SUBMITTING_PATCHES file directs)
that there were a number of violations reported. This makes it difficult
to see violations I might have introduced. This commit corrects all
pylint violations in the repo script.

First I ran this to clean up the formatting:

 autopep8 --max-line-length=80 --indent-size 2 repo

Following that the following violations remained:

% pylint --rcfile=.pylintrc repo
************* Module repo
W:220,21: Redefining name 'init_optparse' from outer scope (line 156)
(redefined-outer-name)
W:482, 2: No exception type(s) specified (bare-except)
C:704, 0: Old-style class defined. (old-style-class)

For line 220, the parameter to _GitcInitOptions was renamed so as not to
mask the init_optparse global.

For line 482, a pylint directive was added to disable the bare-execpt
violation for just that line.

For line 704, the _Options class was changed to subclass object.

Additionally, the comments at lines 107-113 were spaced out to line up
with the comment at line 112 that autopep8 moved.

This script now has a pylint score of 10.0
