Hm. The behavior of \fP\fP is actually intended and can be used
non-pathologically:
  One \fBtwo\fP three \fPfour\fP five \fPsix\fP seven.

...but it's rarely used because it's not very readable. I guess this
makes it fall into the same category as interpolating undefined
registers as 0, which some code also relies on, but is often not
intended, hence it having an optional warning category 'reg'.
