I think you believe correctly ;)

I'd like to, but the program as used for svn currently shows current
local revision and only updates if there are differences with a remote
revision.
If possible, I'd like to keep behaviour the same for git...
But I agree, it might be simpler just to do a pull..

Exactly what I needed, thanks. I knew it must be possible, but just
couldn't find it.

Dankie,
