If we aren't using CVS tagging features, it just falls under personal
preference.  If we are, it is easier to import all the changes from
the branch to the trunk, tag it is 'import_to_trunk_N' and then
next time something changes just look at the diff between the
'import_to_trunk_N' tag to now, mark as 'import_to_trunk_N+1', rinse
and repeat.  Doing it w/ tags has the benefit that you can do
a one-liner that says 'try to import any changes from the branch.'
