I think the "how" has been answered but not the why. Generally revision 
numbers are kept in a file that's included in the build and which has 
tags in it that SVN updates. Updating other files does not change the 
revision number in that file, so even if lots of files change the -v 
revision number won't be different. I guess "make up" forces that file 
to contain the latest rev number.
