[RFC PATCH v2 2/4] rebase: prepare cmd before choosing action

[Andrei Rybak <rybak.a.v@gmail.com>]

When git rebase is started with option --exec, its arguments are parsed
into string_list exec and then converted into options.cmd.

In following commits, action --edit-todo will be taught to use arguments
passed with --exec option.  Prepare options.cmd before switch (action)
to make it available for the ACTION_EDIT_TODO branch of the switch.
