Yeah, a HINT listing the allowed spellings of the unit would go a long
way here.

It's case-sensitive.  We had that argument already, but I still think
this decision was wrong.

Looking at the code, spaces before the unit are allowed, but not spaces
within or after.  I agree with disallowing embedded spaces, I think,
but not allowing trailing spaces is inconsistent with our practice in
other cases (in particular, these very same variables, when written as
pure numbers...)
