[PATCH] Working revisions

[Paul Emms <pa...@calleo.com>]

Here are two patches that allow access to working revisions on the main
branch.
Is branch version numbering implemented correctly yet ? I am assuming you
want
something along the lines of CVS so that version numbers are unique across
all
branches: in that case each node would have an even number of dot separated
digits e.g
1.2.2.1 for a branch off version 1.2
