[PATCH 1/4] git p4: bring back files in deleted client directory

[Pete Wyckoff <pw@padd.com>]

The code to auto-create the client directory, added in 0591cfa
(git-p4: ensure submit clientPath exists before chdir,
2011-12-09), works when the client directory never existed.

But if the directory is summarily removed without telling p4,
the sync operation will not bring back all the files.  Always
do "sync -f" if the client directory is newly created.
