Another stderr/stdout question

[Phil Holmes]

The regtest option-help.ly emits the help text for ly:set-option.  The idea 
is that the logfiles will thus be compared in the regtest checking.  Only 
problem is that the list seems to go to stdout and the logfiles are produced 
from stderr, so no checking actually occurs, AFAICS.  This has the side 
effect (which is how I spotted it) of sending the help text to the terminal 
screen rather than to logfiles, when make doc is run.

What do we think: is it going to the wrong place, or should we do something 
else with the regtest and make doc?

While I'm here - anyone know which regtest produces this:

(make-music
 'UnrelativableMusic
 'element
 (make-music
   'SequentialMusic
   'elements

and more?
