OK, I have no strong opinion on this but I don't think cut is very 
portable, sed is much more common. But here's anoter version similar 
to your cut way just using the shell only if you like:

REVISION="$(git svn log --oneline -1)" && REVISION="${REVISION%% *}" && 
REVISION="${REVISION#r}" && echo $REVISION
