format-mark function for A, B, C, …, X, Y, Z, Aa, Bb, Cc, …

[Malte Meyn]

Hi list,

sometimes there are more than 25 or 26 rehearsal marks in a piece. 
LilyPond’s format-mark-(alphabet|letters) function and friends continue 
after X, Y, Z with AA, AB, AC, …

I have never seen this in printed scores. Instead all scores I’ve seen 
continue with doubled letters (the second lowercase): Aa, Bb, Cc. And 
once I’ve even seen … Yy, Zz, Aaa, Bbb, …

I made functions format-mark-(alphabet|letter)-var and boxed and circled 
variants which implement this behaviour (see attached patch). So now I 
would like to know:

Is there an interest in having this behaviour in LilyPond (maybe as a 
variant)? Or have you seen something similar (f. e. everything 
uppercase)? If so, how to name these functions? And would I have to post 
this to bug- or dev-list? They’re not perfect yet, for example I didn’t 
know how to use vector-map ;)

Or is this something for openlilylib instead of original LilyPond?
