Spaces around braces

[Simon Albrecht]

Hello,

I keep noticing that many users don’t put any spaces around { } = etc. I 
recall reading when I had just started working with Lily that it’s 
recommended to _always_ surround these with spaces.
Ultimately, this is a GLISS issue, but is there any striking reason 
right now to request using the spaces? Or does it not actually matter 
except that it un-eases reading foreign code following a different 
convention?

Yours, Simon
