git-p4: support single file p4 client view maps

Browse source 
Perforce client views can map individual files,
mapping one //depot file path to one //client file path.
These mappings contain no meta/masking characters.
This patch add support for these file maps to
the currently supported '...' view mappings.

[pw: one test now suceeds]
