Proposal: require spaces around the dot operator

[Isaac Dupree]

I support requiring spaces around the dot operator, *even if* we don't 
ever end up using it for anything else.

It helps a bit in mentally parsing code, so I try to write that way 
anyway.  So I don't mind making this change.

This change helps us community-wise, having one less issue for us to 
concurrently agonize about as a community while talking about records 
(whether or not we decide to use dot, it makes the conversation less 
complicated).
