This only happens if all files are tagged, AFAIK?  I was referring to
adding tags to those files that actually are modified, to tie each
commit and each merge together so it can be viewed as a single change
at a later point in time, instead of being viewed as one change for
each file, with no usable way to automatically find out what other
changes was done at the same time.  This do not require modifying all
untouched files unless I've totally misunderstood the way RCS tags work.
