OK, if there is the current branch _among_ the remotes and we are
synching with the local repository, we reject to muck the
configuration for 'local' branch with any of the refs in 'remotes'.
Makes sense.
Just FYI (because there is nothing actionable on your part), there
is another topic in flight that wants to change the warning message
to be phrased like so:
_("not setting branch '%s' as its own upstream")
i.e. without capitalizing the first word, and without finishing the
sentence with a full stop. I'll make the conflict resolution to
read as such.

Likewise.

The above is currently correct but it often is an invitation for
future bugs to use double-quotes around the executable part of
test_expect_success. We can always write ' --> '\'' to enclose the
thing in a pair of single quotes when we start needing to refer to
$shell_variables in the executable part, so let's take the above
patch as-is, but something to keep in mind.
Thanks, queued.
