I re-read the original and Peter is really accessing the same
repository, only over different transports.  Cloning via ssh:// but
later deciding to push via ssh:// but to fetch via https:// (or vice
versa; the important point is that clone was done over a transport
that is "wrong" for future fetching).

Of course, if you cloned via a wrong transport that is not suitable
for whatever reason for later fetching, you would need to have a way
to "swap", so the observation I made in the message I am following
up on does not apply to this thread at all.  Please scratch all of
the above.

Coming back to the topic, how common would this "oops, I cloned via
a wrong transport" be?  I am not opposed to giving a recovery method
for gotcha that does not happen very often, but if such an addition
adds undue confusion factor for people who use "set-url" for more
common cases, that would be a bad trade-off.
