It's useful if people don't want to commit their changes before  
reviewing.  (Actually, I use mq to manage my changes, and it does  
pseudo-commits.)

The mercurial way to say this sort of thing is 123:124, where the  
numbers name two revisions.  Perhaps that can be integrated into  
webrev, although it would touch a couple dozen lines.
