In this situation, you can use "g.remove -f ..." to ignore the warning
and remove the map anyhow.

The first g.remove should have removed the entry from the reclassed_to
file; I'll look into why it didn't.

However, if another user creates a reclass of one of your maps, it may
not be possible to remove their reclass map first, so sometimes using
the -f switch is necessary.
