Fails if output language is not English

[gareth-rees]

Many features work by parsing the human-reading output from Perforce. These features will break if the output language is not English, which can happen if the server has been set up with translated messages, and if P4LANGUAGE is set accordingly.

In some cases (where the output is never seen by the user) we could just pass the -L en option to the Perforce client. But what about the cases where the output is parsed and then shown to the user?

I don't propose to work on this unless someone actually encounters the problem (and is prepared to help me debug it). So please comment on this issue if it affects you.
