Yes, but the point was the docs clearly state that Ask is not
implemented in Fabric, thus it's a binary choice between auto-add and
auto-reject, thus the single Boolean config option :) It was an
attempt at highlighting "hey, if you're used to SSH, you know of the 3
options -- but we only implement 2 of them right now."

Correct, abort_on_prompts is an acceptable workaround, but only if
you're OK with other prompts causing aborts.

The mentioned fix has been committed and worked for me, if you want to
test it yourself you can grab the git repo or the tarball for the 1.3,
1.4 or master branches. Otherwise it'll be out next bugfix.

Thanks! Glad it's working out for you.

Best,
