[Paul Vincent Craven]

The CompareVersionBis, DecreaseVersion, and
IncreaseVersion subroutines don't work with branched
version numbers. This prevents 'diff' links in the HTML
for working in branches.

When doing a report between version 1.59.2.3 of a file and version 1.60 of a file, the output included versions 1.1 - 1.60. This is very annoying. Please show this bug a little love and squish it :-)
