[PATCH V2 2/2] git-p4: improve client path detection when branches are used

[Vitor Antunes <vitor.hda@gmail.com>]

A client view can be used to remap folder locations in the
workspace. To support this when branch detection is enabled,
it is necessary to get the client path through "p4 where".

This patch does two things to achieve this:

 1. Force usage of "p4 where" when P4 branches exist in the
    git repository.

 2. Search for mappings that contain the depot path, instead
    of requiring an exact match. To guarantee robustness,
    paths only match if ending in "/...".
