[PATCH 2/2] git-p4: do not decode data from perforce by default

[Andrew Oakley <andrew@adoakley.name>]

This commit is not intended to change behaviour, any we still attempt to
decode values that might not be valid unicode.  It's not clear that all
of these values are safe to decode, but it's now more obvious which data
is decoded.
