Thanks.  I added that link to the bug-tracker.
I see no support there for 'eksik bakiye' being a limma flat by a comma, 
though.  If you mean the 256/243 limma lowered by 80/81, that is not at all a 
simple ratio, and would not seem to be an alteration that comes up in any 
harmonic theory of music.

We could include regular.ly in LilyPond if Graham wants that.  It does seem to 
serve the community better at the microtonal website, where there is more 
context for theory of tuning.

'makam.ly' can retune the scale for Turkish makam with one hard-coded line, 
which might be more appropriate in this case.

(Notice that LilyPond's current makam.ly effectively uses the 54-ET system 
mentioned a few posts lower in the link you gave.  I can't read Turkish, but 
from the emoticons I suspect they are saying 53-ET fits the music better.)
