Re: Notation manual - 1.3.3 Expressive marks as lines - glissandi

[Simon Albrecht]

Sorry, but what are you playing at with such an e-mail on the -devel list?
First, it’s a little bit offensive considering that – as you very well 
know – all people bringing Lily to you are only volunteers who do their 
very best to make her as good as possible.
Second, this is a _developers’_ list. So if you have a technical 
question at developing LilyPond, or want to propose a patch, then you 
can come here. For a documentation suggestion as this the bug list is 
the right place.
And you’ll be wise to provide a more precise description of the problem 
with that example in the docs and why your proposal solves that problem. 
‘side effects have buggered everything else up’ and ‘mess up royally’ 
are so vague expressions that you basically expect others to figure out 
themselves what exactly these side effects are, and why the snippet 
doesn’t apply to your use case.
The whole story of your pain with this issue may go to the user list 
then – maybe you can get some advice there.

Best, Simon
