Oh, indeed, we could also just use vc-svn-global-switches rather than
introducing a new var.  But as noted, changing such user var's default
is likely not to work for all users.

If the default should be "don't use --non-interactive", then we can just
drop the hardcoded --non-interactive and tell people to adjust their
vc-svn-global-switches if they want to pass --non-interactive.

So, could someone explain to me when --non-interactive is needed?
The report seemed to be for w32, does that mean that it's only ever needed
for w32, or is it also sometimes needed under GNU/Linux?
