Some info about the Extended Helmholtz microtonal accidentals [1] that Graham 
mentions:

It might be nice to have some of the 5-limit intervals in [1]. The 5-limit is 
the most important one, as this is what a Western orchestra typically adapts 
towards.

In a LilyPond implementation, one can choose E53 (53 equal temperament) as an 
approximation of Pythagorean tuning, and then approximate the syntonic comma 
81/80, about 21.506 cents, with one E53 tonestep, also called a comma. The 
approximation is so good that the difference barely can be heard in 
simultaneous sounding notes.

The interval of a sharp or flat in E53 is 5 commas, so it makes it possible to 
have the single- and double-arrows in [1] implemented in E53. The other ones 
would end up in E53 enharmonic equivalence.

FYI, E53 is also used in the description of Turkish music, and might be 
suitable for Persian (with koron and sori glyphs added), and in Arabian music. 
Currently, the files for these use something else: ETs that are multiples of 
12, due to limitations in past versions of LilyPond.
