Consider making formulae and expressions consistent

[j9t]

Mathematical expressions use an inconsistent mix of both formatting (spaces) and characters.

Examples for space inconsistencies (copy view):

• “length / (r1 + r2)” uses spaces between operators
• “w×h” use no spaces
• “(size-1)×avg + max” uses both spaces and no spaces

Examples for inconsistencies in type of space (code view):

• length / (<var>r1</var> + <var>r2</var>) uses spaces
• <var>size</var>&times;<var>avg</var>&nbsp;+&nbsp;<var>sbw</var> uses no-break spaces

Examples for character reference inconsistencies (code view):

• <var>rows</var> × <var>pixelsPerRow</var> uses “×” for multiplication
• (<var>size</var>-1)&times;<var>avg</var>&nbsp;+&nbsp;<var>max</var> uses the × character ref

I think generally we want to use normal spaces to separate all these things. The Encoding Standard should be pretty consistent about this.
