I should have know better than to copy as I did from the source code 
without analyzing it sufficiently! In typo-spa.mkiv I found:

    \setupcharacterspacing [frenchpunctuation] ["003A] [\c!left
    =.25,\c!alternative=1] % : ...

I see (now) that the space disappears when the \c!left macro is 
processed. Mea culpa. I owe you a beer.
