spacing about latexml HOT 4 CLOSED

Those commands are preserved in text, but discarded in math.
It's actually a bit tricky, since the goal is to parse the
math, as far as possible. Even ignoring the fact that spacing
conceivably carries some semantics, their presence interferes
with any remotely writable grammar! So, currently, they
get removed before parsing.

I do have a crude mental model of how they might be preserved:
Rather than throw them out, they would be attached to adjacent
symbols (preceding, following?), carried through the parse,
and then turned into something reasonable during final processing
(eg. mpadded for MathML ?). It really isn't clear that the
padding would be in the right place, though, and needs some thought.

So, this is on the back burner for now....
but I'll leave the ticket open as a reminder; Thanks!

Maybe ?

I don't know anything about MathML really, so I leave it to you.
Thanks for responding!

Also I'm happy to see that spaces inside \text{} are working, so I can get good output from e.g. [f(x)=4\text{ when }x>0]. I don't think that was working in older revisions, which was a big part of my unhappiness about spacing. Or maybe I was using \mbox instead of \text or something...

I finally was able to focus my attention on this one (also).
Basically I needed to accept a workable, even if not-quite-correct,
solution: before we throw away spacing hints, we copy the width
to the preceding token as an rspace; That gets carried through
until it gets converted to presentation MathML, and gets wrapped
by an mpadded when needed. It seems to work.

Sorry for the delay, and thanks for the report.
