Factor out the command line processing in git-rebase--interactive.sh to git-rebase.sh. Store the options in variables in git-rebase.sh and then source git-rebase--interactive.sh.
Suggested-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Martin von Zweigbergk <martin.von.zweigbergk@gmail.com> --- Changes since v1:
* As suggested by Johannes Sixt, source git-rebase--interactive.sh instead of executing it.
Since this removes the command line processing from git-rebase--interactive.sh, it completely changes its command line interface. Since it is not listed as even a plumbing command, I hope this is fine.
