git-p4: show detailed help when parsing options fail
When a user provides invalid parameters to git-p4, the program
reports the failure but does not provide the correct command syntax.
Add an exception handler to the command-line argument parser to display
the command's specific command line parameter syntax when an exception
is thrown. Rethrow the exception so the current behavior is retained.
