[tex4ht] thin space to non-breaking space?

[Michael A. Allen]

Is it possible to configure tex4ht to convert the thin space \,
into a non-breaking space? At the moment \, is converted into an
ordinary space. [There is actually a thin space character in html but
it seems many browsers don't recognize it, so converting to some sort
of ordinary space seems like the best option for the time
being. Ordinary TeX treats \, as non-breakable.]
