Hi, all,

Hans has done some work on autopunctuation which made it into
yesterday's beta (2012.12.03 11:33). This includes a 'set it like I
type it' mode people have been asking for.

There are now three options to \setupmathematics[autopunctuation=...]:
* autopunctuation=no — default TeX behaviour. Commas get a thin space,
periods get nothing.
* autopunctuation=yes — manual control for commas. Commas followed by
a space get a thin space; periods, and commas followed by something
else, do not.
* autopunctuation=all — like `yes`; and periods, too, get a thin space
unless suppressed

Example code below, example output attached, and the behaviour is documented at
http://wiki.contextgarden.net/Command/setupmathematics

Cheers,
Sietse
