More related, yes, but %F does do the equivalent of %{%} internally (I
didn't know what %{%} did when I wrote the commit message).

For reference bash does have the equivalent of that with \[ \], but
that's specific to bash and it's converted to \001 \002 internally
which is what readline understands. A prompt function (like
__git_ps1()) cannot return \[ \].

> 3. Escapes for ctrl-a and ctrl-b also work?  Or this is explicitly looking for \001 \002 ?  Any possible conflicts?

^A ^B are another way to say \001 \002 is it not? Or \x01 \x02. At the
end of the day are the same values.

I don't know how to echo ^A in order to test though.
