Rewrite `squash` and `fixup` handling in `do_next` using the sequence
pick_one
commit
in order to test the correctness of a single `do_squash` or
parameterised `do_pick` and make the subsequent patch reimplementing
`squash` in terms of such a single function more readable.
Do not call `rm -f "$GIT_DIR"/MERGE_MSG` since it has no effect on
the state after git-rebase--interactive terminates. The option `-F`
makes git-commit ignore `MERGE_MSG` for the log message. If
git-commit succeeds, `MERGE_MSG` is removed, and if it fails,
`MERGE_MSG` is overwritten by the error sequence `die_failed_squash`.
In summary, removing `MERGE_MSG` neither influences the squash commit
message nor the file state after git-commit returns.
Moreover, `pick_one` ignores `$GIT_DIR/SQUASH_MSG` and does not touch
`$squash_msg` so that it is correct to execute `pick_one` immediately
before git-commit.
Might be squashed into the subsequent commit.
