I tried implementing this change (a simple one-line addition) but it
breaks some other pieces of code block evaluation (inline blocks) which
assume that ":results silent" will not affect the contents of the
buffer.

For not at least I think it would be preferable to leave the meaning of
silent to be "do nothing to the buffer" rather than to remove any
possibly pre-existing results.  Possibly at some point in the future
after I've fixed results removal for inline blocks we should revisit
this decision.
