Aaron -- thanks for the pointer!  It's interesting to see what each
SCM does in this situation.  By default, tla and bk also detect the
conflict.  In tla, it can be resolved via tla star-merge --three-way. 
In bk, I found that if I keep the repo in checkout:edit mode, and do
bk unedit prior to bk pull, when identical changes are already
injected by other SCMs, it does the trick.

So, only darcs at this moment has no easy way to avoid identical
changes conflict and has to go first in a pull sequence!  (It used to
be bk.:)
