Fix the last few precedence tests failing in t7601 by now implementing
the logic to have --[no-]rebase override a pull.ff=only config setting.

There are both merge and rebase branches in the logic, and previously
both had to handle fast-forwarding. Merge handled that implicitly
(because git merge handles it directly), while in rebase it was
explicit. Given that the --ff-only flag is meant to override any
--rebase or --no-rebase, make the code reflect that by handling
--ff-only before the merge-vs-rebase logic.
It turns out that this also fixes a bug for submodules. Previously,
when --ff-only was given, the code would run `merge --ff-only` on the
main module, and then run `submodule update --recursive --rebase` on the
submodules. With this change, we still run `merge --ff-only` on the
main module, but now run `submodule update --recursive --checkout` on
the submodules. I believe this better reflects the intent of --ff-only
to have it apply to both the main module and the submodules.
(Sidenote: It is somewhat interesting that all merges pass `--checkout`
to submodule update, even when `--no-ff` is specified, meaning that it
will only do fast-forward merges for submodules. This was discussed in
commit a6d7eb2c7a ("pull: optionally rebase submodules (remote submodule
changes only)", 2017-06-23). The same limitations apply now as then, so
we are not trying to fix this at this time.)

The warning about pulling without specifying how to reconcile divergent
branches says that after setting pull.rebase to true, --ff-only can
still be passed on the command line to require a fast-forward. Make that
actually work.

There were already code checking that --rebase was incompatible with
a merge of multiple heads. However, we were sometimes throwing warnings
about lack of specification of rebase vs. merge when given multiple
heads. Since rebasing is disallowed with multiple merge heads, that
seems like a poor warning to print; we should instead just assume
merging is wanted.
Add a few tests checking multiple merge head behavior.

The interaction of rebase and merge flags and options was not well
tested. Add several tests to check for correct behavior from the
following rules:
* --ff-only vs. --[no-]rebase
(and the related pull.ff=only vs. pull.rebase)
* --rebase[=!false] vs. --no-ff and --ff
(and the related pull.rebase=!false overrides pull.ff=!only)
* command line flags take precedence over config, except:
* --no-rebase heeds pull.ff=!only
* pull.rebase=!false vs --no-ff and --ff
For more details behind these rules and a larger table of individual
cases, refer to https://lore.kernel.org/git/xmqqwnpqot4m.fsf@gitster.g/
and the links found therein.

When we cannot figure out how wide the terminal is, we use a
fallback value of 80 ourselves (which cannot be avoided), but when
we run the pager, we export it in COLUMNS, which forces the pager
to use the hardcoded value, even when the pager is perfectly
capable to figure it out itself. Stop exporting COLUMNS when we
fall back on the hardcoded default value for our own use.
