Thomas Arendsen Hein <thomas@intevation.de> [Thu, 16 Nov 2006 08:51:22 +0100] rev 3671
Use nullrev+count instead of count-1 in a newly introduced expression.
Before that repo.changelog.tip() was used, but this yields a node.
Of course many more places should be changed like this, this was just done
as an example.
