John Stiles d68069019b Fix whitespace when commas are used in a binary-expression.
Previously, any code which emitted a binary expression would always emit
a leading and trailing space. This caused comma expressions to look
goofy: `foo() , bar();` instead of `foo(), bar();`.

Operator::operatorName() now returns the operator token with appropriate
whitespace around it, and tightOperatorName() is a new method which
omits the whitespace. Functions which assemble binary expressions
should now concatenate `x + operatorName() + y` instead of hard-coding
`x + " " + operatorName() + " " + y`. Prefix/postfix expressions should
use `tightOperatorName()` because otherwise negation looks bad (` - 123`
instead of `-123`).

Super low priority, but it was easy to fix.
