status: support --porcelain[=<version>]

Browse Source 
Update --porcelain argument to take optional version parameter
to allow multiple porcelain formats to be supported in the future.

The token "v1" is the default value and indicates the traditional
porcelain format.  (The token "1" is an alias for that.)
