Jonathan Tan 42d418df90 (various): document from_promisor parameter
88e2f9ed8e ("introduce fetch-object: fetch one promisor object",
2017-12-05) plumbed through the from_promisor parameter but did
not document it everywhere it appeared. Add the documentation.

(It also plumbed through the no_dependents parameter, but I have left
that alone because it is being removed in a commit under review [1].)
