Conventions for setting the degrees of temperature symbol vary; see http://en.wikipedia.org/wiki/Degree_symbol#Typography and references therein. In most professionally published works that I've seen, there is no space between the number and the °, or between the ° and the C.
I agree they vary, and no space before the °C is quite common (and frequently my own practice too). However in setting default behaviour for Context I am inclined to favour conforming to international standards, where they exist (but a \setupunits override it probably called for).
I have no opinion as to what the default behaviour should be, but it would certainly be useful to have spacing for ° temperature configurable separately from that for other units. Pont
