2011-06-26 22:47 AEST by Arthur Barrett - A new option (only to CVSNT server) that passes the commit id back to the client.

The commit id is known right at the start of the transaction (it's the same as the session id) so commit can 
easily ask for it and get the result before the 'process' stuff.

If this option is supported by the server, it'd be easiest to always ask for it, and then if the --show-
commitid option has been specified then it can be displayed on the stdout after commit has completed.

Other options include using the cvsgui protocol or some other technique to pass this to the GUI...
