It's possible that all that would be necessary is to add a routine at
the bottom of `nnimap-transform-headers', to sort the buffer text. The
SEARCH command is handled differently, I believe.

I don't think modifying gnus-range is a good idea -- if that code
requires sorted ranges, we should just make sure it's always given
sorted ranges.
