Sigh.  It seems that I'm not able to write what I really want.
Another try.  I know that I can tune the clefs, but this isn't my
problem.  Please concentrate on the process of transposing!  All music
I enter in LilyPond is written as it sounds, including Horn (so I
basically write Horn in C).  This is fine for the full score, and
indeed almost all full scores from today are scores in C.  For
creating the horn parts, I use

  \transpose f c'

to get a horn part in F, and here is the problem: Horn parts converted
to bass clef are written a fifth higher, but according to the
classical rules it should be a fourth lower.  My suggested property
controls \transpose, not the clefs: Notes found in bass clef should be
transposed an octave down additionally.
