I don't understand the distinction that you are attempting to draw
between "atomic" and "non-atomic" commands.  For example, in the
following command list:

    pick 1111111
    squash 2222222
    fixup 3333333

the "pick" command doesn't seem very atomic, because the *end* result of
the three commands is a single commit that is affected by all three
commands.  Furthermore, if we change the example to

    pick 1111111
    squash --reset-author 2222222
    fixup --signoff 3333333

then isn't it clear that the user's intention was to apply both options,
"--reset-author" and "--signoff", to the resulting commit?  In other
words, it seems to me that any options on such a chain of lines should
be collected and applied to the final commit as a whole.

The new user-exposed options should be documented in the git-rebase(1)
manpage and probably also in the help text that is appended to every
"rebase -i" todo list.
