I know. I tried to explain myself and the situation but did not succeed.

That's what I tried to do with the patch. I guess the patch is now
outdated since it's made to a revision far in the past.
I admit that failing to get the username on a Linux/Unix system or
on a winNT based system _is_ a fatal error, it is the normal behaviour
on win98 based systems (or any other system where you don't have
to logon).

Agreed.

Right. Also the command line client would also _ask_ for a username
and not error out.

It'll do that.

I may miss something here but I can't see what this should be good for?
For the command line client is is a good option to pass --username and
--password so you can use the client with a script. But TSVN is not
scriptable and user interaction is always possible.

If (1) is fixed, everything will work fine with TSVN (and the CL client
too).

I think the summary is ok. Thanks!
