In dont't really know why you think it should render differently. 
Everything TeX is supposed to ignore white spaces in math, AFAIK. 
If you want a space in math, you need to force it, like this: 

\setupmathematics[autopunctuation=yes]

\starttext

$(2,\ 5)$ versus $(2,\ 5)$

\stoptext

Works like a charm, Hans! Sorry I took so long to test...
I copied file-job.lua from the GIT repository, and changed my tex
files to use toppath:/path/to/file.

For example:
https://bitbucket.org/andrecaldas/math-video-classes/src/b743f22e4f567662ac55c1ac7dc1b6d13362e11d/src/products/assorted.tex?at=default

Really nice! Thanks!! :-)


Cheers,
Andr? Caldas.

If I get it correctly, the following two formulae should render
differently - and they don't.  What is going on?

\setupmathematics[autopunctuation=yes]

\starttext

$(2,5)$ versus $(2, 5)$

\stoptext

\nT is an unknown command.

Will this be in the core, or is it just a fix for Andreas? I.e: should
we document toppath() as a core command, or as a snippet?
(Not that we have a general space on the wiki for snippets yet, but we
need one and we will have one. Somethine in the next two weeks I'll
write a "State of the Wiki" laying out what we have, what we don't
have, and what we want next.)
