For stuff like LT@<number> you already sort 1000 numbers into something
like 200 hash buckets (don't remember the exact ratio: it was different
with roman numerals but not all that much better IIRC).  If somebody
then uses a similar indexing scheme for MR@<number>, he'll share exactly
the same hash buckets.

I thought I wrote some Elisp code evaluating this kind of thing ages ago
but cannot find it on my current disk.
