As was already said in the thread you're linking to, this isn't a
Windows-specific git-issue. CC'ing the main Git mailing list, where
this discussion belongs.

But I don't think it should check GIT_ASKPASS, GIT_ASKPASS isn't a
general-purpose dialog-box hook, it's a hook for getting *passwords*.
To allow git-svn to query the user of a non-terminal user, another
mechanism would probably be created. But in any case, I we should do
something other than just waiting if we're not connected to a TTY. I
don't really know Perl that well, but perhaps something like this does
the trick?
