issue classification: priority guidelines

[Janek Warchoł]

Hi,

I've read Issue classification and i think it would be good to add one
more guideline concerning priority: i believe that the priority should
depend on how widespread the issue is. Even minor problems concernning
some basic elements (that will probably happen many times in even a
single score) should be more important than an ugly collision that
came from a contrived example and is not likely to happen more often
than once or twice in hundred scores, or is related to very specific
and complex engraving situations.
Do you agree?

cheers,
Janek
