You are right, I had a wrong idea of the bug reason, thought that what
failed was update-alternatives re-setting the same alternative without
previously removing it, but is that -1 with its fpc<->pc typo causes,
when upgraded, two different values for the slave corresponding to the
same master value.
FYI, I have tested with a homemade 2.2 just built with a
mv fp-compiler.preinst fp-compiler.prerm
from my previous -2.1 version, that is, without any preinst stuff.
Upgrading from -1 to -2.2 or from -1 -> -2 -> -2.2, I get for the first
run,
--------------

But after an inmediate second run,

Seems that to make things really smooth something in the preinst is
needed in this case to work around the bug introduced in -1, just
reconfiguring after -2.2 does not help.
