The problem is the svn to cvs exporter doesn't properly tag the
existing revisions for releases, but rather checks in a brand new
revision and tags that. So, when you switch branches (such as release
to stable) with CVS, all the $FreeBSD$ tags change, and you get the
false positives in mergemaster.

Using your example (etc/periodic/daily/300.calendar), there is: for RELENG_8_1 for RELENG_8
1.5 for MAIN (current)

There are many more 1.5.x revisions for other branches. These
shouldn't exist - the file hasn't changed since 2000 and 1.5 should
just be tagged with for all releases since then.
