Details:
The "f" scale unit (thanks to Ingo Schwarze for this new terminology) is
applied only to dimensionless quantities (the intensity of a luma or chroma
channel in a color space), and is itself dimensionless.
While it's _possible_ for people to use "f" with a length measurement, it's
likely not done seriously in practice except in error.
See how easy it would be to get src/roff/troff/number.cpp:552-581 to handle
this.
It would also be good to reject the complementary form of nonsense.

A type system was lying right there the whole time... :-/
