show-break-places, a fantasy

[from -user to -bug]

Hello,
  I come up with a problem (only for the blind). When extracting parts, sighted 
people can check whether the page turn is disturbing the flowing music and 
troubling the players, but for me, I have to ask an assistant for help, since 
Lilypond can't export Musicxml, or Musescore can't open Lilypond file. 
Furthermore, if I'm asking an orchestra to play from a middle position other 
than rehearsal mark, they, including the conductor, will search for bar 
numbers, because I can't tell them which page and which system to begin. Then 
I'm thinking of an option for accessibility: if turned on, the log file will 
write out number of the bar at the beginning of every system in a page as a 
single line, then give a new line for a new page. For example:
#(ly:set-option show-break-places)
Then in log file:
drawing systems...
(because I think the result only comes after generating graphics)
[1][5][10][16][19][24]
[28][34][41][45][50][60]
