This has a side effect of making all the code locations that used to
refer to option_origin much easier to read, like ...

... this place ;-)  Happy.

clone.defaultremotename is a single valued configuration variable,
and this correctly implements the "last one wins" behaviour (but
previous remote_name will leak every time clone.defaultremotename
is seen in the config stream).

Also this code arrangement is not quite satisfactory.  It means that
we cannot re-read any configuration variable that does not have an
accompanying command line option.  I thought the whole point of
doing the write_config() was so that anything came from the command
line option can be written back to the configuration file, so I am
not sure what the harm would be to update remote_name from the
configuration whether option_origin is used or not here.  Perhaps
add "clone.defaultremotename" to the set of configuration setting
write_config() uses, when --option is given from the command line,
and remove this special case?

By the way, I now realized why 2/4's "read twice" is OK.  init_db()
calls create_default_files() and we do clare the cached configset by
calling git_config_clear() there.

Thanks.
