   I plan to use this policy.
   That is, if 'darcs replace' suggests I might want to use --force, then I
will not use 'darcs replace'.  Instead I will manually change the tokens of
interest, (and record) OR create an alternate name to replace with.  It
seems the second option is certainly preferable from the perspective of
automating replace.
