Well, no server communication is required to convert the string 'PREV'
into an actual number. We just grab the 'last-changed-revision' field
from .svn/entries, and then subtract 1.

Then, later on, we probably use that number when talking to the
repository. But there's no need to ask the repository for
history-tracing.

Sure, file an 'enhancement' request, but in 'unscheduled' milestone...
so we remember to discuss it on the dev@ list later on.
