[PATCH] Accept --force for switch --relocate was Re: Possible SVN Relocate bug

It does accept it in trunk though, but it doesn't do anything for relocate.

The patch below should do the trick here. The only subjective point
is whether we think it's kosher to accept a NULL baton in
svn_wc_relocate2 - or whether we should still call the function and
have validator_func always return TRUE for the check if we were asked
to --force it. I think it tends to be a bikeshed - so I went behind
Door #1. *shrug*

If no one has any objections/comments in a reasonable amount of time,
I'll commit it.

BTW, the current help message for 'svn switch' is way way too verbose
for --force, but I'm not going to editorialize that now. No human
being could ever make sense of the current help message, IMHO.

Thanks! -- justin

be switched.
