[execnet-dev] Help connecting through ssh jump host

[RonnyPfannschmidt]

Hi prasanna,

execnet has grown support to do the following

hop = makegateway("ssh=a//id=hop")
gw = makegateway("ssh=b//via=hop")


as for the first example you gave,
that looks like it might have worked by accident,
for clarification please bisect at which version it worked and broke so
we can link it to a feature induction
