The only thing that makes sense is to get the pairs via M-p/M-n and
up/down.  Of course, that clashes with the current behavior and hence
prevents access to "TO-history" in the FROM case and to "FROM-history"
in the TO case.

But if we only do that for the FROM prompt (which is already a "FROM or
FROM/TO pair" because of the behavior in case you just hit RET, and
would turn even more clearly into a "FROM or FROM/TO pair"), I don't
think it's that bad:
- You still have access to the "TO-history" in the FROM case, indirectly
  (by browsing the corresponding FROM/TO pair and erasing the FROM and
  the separator).
- You still have access to the FROM-history in the TO case, just as before.
