Thanks. I'll reword the proposed commit log message before queuing, because it won't make _any_ sense to talk about the search order before telling what these things that are searched would do, or why they are useful things to have.

    "rebase -i": support special-purpose editor to edit insn sheet

    The insn sheet used by "rebase -i" is designed to be easily editable by
    any text editor, but an editor that is specifically meant for it (but
    is otherwise unsuitable for editing regular text files) could be useful
    by allowing drag & drop reordering in a GUI environment, for example.

    The GIT_SEQUENCE_EDITOR environment variable and/or the sequence.editor
    configuration variable can be used to specify such an editor, while
    allowing the usual editor to be used to edit commit log messages. As
    usual, the environment variable takes precedence over the configuration
    variable.

    It is envisioned that other "sequencer" based tools will use the same
    mechanism.
