Well, now you're falling into the world of heuristics to try and handle
the inconsistent mix of rules used by various authors.
You're obviously free to go there, but don't count me in.

I feel that this anecdote validates my intutition that we want
sin a / 2 to be sin(a / 2), and such. The ugliness of the double space
hack is proportional to the depth of someone's regret, which he or she
used to justify coding the hack.
