I think this can be fixed by using diff3 instead of merge, I just haven't
sat down and figured out the correct incantation.
That said, I think that having a not-quite-working rcs (OpenRCS) in base
is worse than having no rcs. If OpenRCS is improved as per Xin's notes
then just switching over is probably the path of least resistance.
I guess I see the following options:
1) Just leave GNU RCS in the tree.
2) Improve OpenRCS so it can be swapped in.
3) Remove RCS dependencies from other parts of the tree (e.g. etcupdate)
and import just a /bin/ident binary (perhaps from OpenRCS).
Both 2) and 3) require some work. I suspect 3) requires less. :)
