The previous commit ignores the value of --recurse-submodules if
--negotiate-only is given. Since non "no" values of --recurse-submodules
are not supported with --negotiate-only, make cmd_fetch() check for
this invalid combination and die.
This is unlikely to affect internal usage of --negotiate-only, but it
may be helpful for users. We may also want to discourage users from
using --negotiate-only altogether because it was not intended for them.

+This is incompatible with `--recurse-submodules[=yes|on-demand]`.
Internally this is used to implement the `push.negotiate` option, see
linkgit:git-config[1].
