svn commit - mysqldoc@docsrva: r1940 - trunk/tools

Author: paul

New Revision: 1940

Log:
Originally, get-svn-revision displayed the local revision number.
This patch enables it to get remote (parent) repository revision, too.
By comparing local with remote revision number, we'll be able to determine
whether there are revisions to be pulled without actually pulling them.
(Kinda like bk changes -R.)
