Clarification. Here I am suggesting that a part of the logic in the
earlier assignment to move_fetch_to_push should become a similar
call to die(), detecting a competing and unsatisfiable wish, rather
than getting silently ignored.

Also, additionally, since there is no use to have two or more URL,
because unlike "git push $there" that can push to two places,
fetching from two places into the same set of remote-tracking
branches would not make sense, --move-pushURL-to-URL-and-set-pushURL
operation that is the symmetry of what the patch under discussion
proposes should fail instead of creating an extra URL entry, breaking
an apparent symmetry.

URL (plus optionally pushURL) split was done because most everybody
were fetching from and pushing to the same place; it would not have
made any sense to have fetchURL and pushURL that are separate, as
that would have forced everybody to have both, when majority of the
users would have to set them to the same value.
Quite honestly, tweaking URL and/or pushURL is not something you'd
do every three months or more frequently, so I do not particularly
feel sympathetic to the cause of this patch, which would allow
setting one to the value that happens to be set to the other one
while setting an arbitrary new value to the other one. Once the
user's need deviates from that single niche pattern, the user needs
to update both, and setting these two independently is quite simple
and straight-forward in the first place. And that same simple pattern
to set two independently can be used without learning this new option.

Hmph. As a system that has fetchURL and pushURL independently and
forces everybody to set both does not make much sense in the first
place, the patch making sense in that context is not a very strong
reason to support it.

If I don't then I do not have to let you know, then ;-)
I do not particularly think it is a horrible idea, but I do not see
that it would be a feature that helps particuarly wide audience.
