Re: # or not before a value

[Mats Bengtsson]

In most situations, the hash sign is optional but can be added without
chaning anythin. Unfortunately, the manual is a bit inconsequent,
for historical reasons. The hash sign indicates that the value should
be interpreted as within the Scheme language, but as I said, this is
normally done anyway.
In your specific examples, though, it seems that you cannot add a
hash sign in the first case (since the construct "2.0\cm" is specific
to LilyPond) and you cannot remove it in the second case (probably
since "-1" is used to add a fingering in constructs like "c-1"). However,
it does work to say \set fontSize = 2, so unfortunately there is no 
simple rule,
except that if it doesn't work without the hash sign you should always 
try to
add one, and vice versa.
