Yea, mea culpa.  I had actually glanced at that but was asking on 
the assumption that I might have misunderstood something about 
the simpler functions -- it was a bit odd that (for example) a 
`post` call whose input data was `void[]` or `ubyte[]` would 
still be treated as text content-type.

In any case, I now have a working solution using 
HTTP.setPostData, so all's well ;-)  Thanks!
