Hm. There are two kinds of errors in git-cvsserver and they should be handled
differently.

If the error is an invalid request (like the quoted one), there should be
normal print, to STDOUT, starting with "E", because it's an error message
that should be sent to the client.

On the other hand if the error is internal error in the script or it's
configuration, than the error should probably be reported via die, *without*
E at the begining (it will be prefixed with location anyway). Such message
will probably end up in the log rather than sent to the client.
