git-p4: normalize indentation of lines in conditionals

PEP8 recommends that when wrapping the arguments of conditional
statements, an extra level of indentation should be added to distinguish
arguments from the body of the statement.

This guideline is described here:
https://www.python.org/dev/peps/pep-0008/#indentation

This patch either adds the indentation, or removes unnecessary wrapping.
