`do_pick` is the git-cherry-pick wrapper in git-rebase--interactive
that is used to implement the to-do list command `pick`. To cater for
the different pick behaviours (like `reword`), `do_pick` accepts
several options not only from the git-cherry-pick but also the
git-commit interface. Add the common option `--edit` to let the user
edit the log message of the named commit.
Loop over `$@` to parse the `do_pick` arguments. Assign the local
variable `edit` if one of the options is `--edit` so that the
remainder of `do_pick` can easily check whether the client code asked
to edit the commit message. If one of the options is unknown, mention
it on the console and `die`. Break the loop on the first non-option
and do some sanity checking to ensure that there exactly two
non-options, which are interpreted by the remainder as `<commit>` and
`<title>` like before.
`do_pick` ought to act as a wrapper around `cherry-pick`.
Unfortunately, it cannot just forward `--edit` to the `cherry-pick`
command line. The assembled command line is executed within a command
substitution for controlling the verbosity of `rebase--interactive`.
Passing `--edit` would either hang the terminal or clutter the
substituted command output with control sequences. Execute the
`reword` code from `do_next` instead if the option `--edit` is
specified.
