I see.  This thesis has the 'eksik bakiye' altering the frequency of the pitch 
by a fraction 3^17 / 2^27.  That would seem to be motivated by mathematics 
rather than traditional harmony.  There is not one example in that thesis of 
its use in music, so it must be very rare.

Since 'makam.ly' has the flat of the same size, it makes sense to have the 
sharp just in case transpose.

Also, the same glyph is used in Sabat's version of Helmholtz-Ellis notation, so 
it seems generally useful.
