This looks broken. Unless I'm very much mistaken the 'if' statement is
always going to be true because the awk statement will always execute
without error. Try: echo "" | awk '{print $NF}' || echo Error

So, the code should probably be changed to:
+if rev=`svn info 2>/dev/null | grep '^Revision' ; then
+	rev=`echo $rev | awk '{print $NF}'`
+       changes=`svn status 2>/dev/null | grep '^[AMD]' | wc -l` 

or alternatively:
+if rev=`svn info 2>/dev/null | grep '^Revision' | awk '{print $NF}'` && \
+   [ -n "$rev" ] ; then 
+       changes=`svn status 2>/dev/null | grep '^[AMD]' | wc -l`

P.S. Looks like the mercurial section is missing some indentation.
