That is a standard space which is fixed for the "texmath"
mathematical language. In the (far?) future, you should be
able to customize mathematical languages.

You are supposed to use "space"; "A-space" is for physical spaces.

Yes, but it is not clear whether "ch r*a" means "(ch r)*a" or "ch(r*a)".
The default intent is "(ch r)*a", but using the same space for " " and "*"
incites the user to put brackets for disambiguating such expressions.
