The orignal article and I believe all of the followups
seem to have missed an important point.  To give something
like "or" the right spacing, you should make it a binary
operator.  Just using an escape into normal mode (however
convenient it may be) won't be correct in all situations.
Sometimes, you may want \mathord or whatever instead.
