HWN:"[\shape] overrides settings for linewidth and indent."
If that is all it does, maybe it should not exist! Better that Lily
be clean in her use of variables...
"Both 1. and 2. are properties, and are already documented in the
'properties' sections. I'll add more index entries"
Sounds fine - I assume you'll do that with a fair bit of the
Horizontal Spacing note I posted a while ago too.
I recommend, however, that a single section in the refman collate all
the spacing systems used by Lily that impact how many pages it takes
for a score, even if a lot of it consists of links to the detailed
descriptions in other parts of the refman, to answer the common
question "how do I get rid of an orphan line".
