The description of this and exisitng <newbase> look very odd. The
usual way to describe an option that take a parameter in the OPTIONS
section is to instead do:
--onto <newbase>::
Description of what --onto option does and how <newbase>
is used in what it does.
--exec <cmd>::
Description of what --exec option does, and how <cmd>
is used in what it does.

Where does this "we split at comma", implying "the user is forbidden
to have a comma in the executed command and its arguments" come
from?
A more conventional way that would be less troublesome in the real
life is to use LF instead in a case like this (and git-rebase.sh
already defines it for exactly a case like this).
I am not sure if that "aexec" is portable outside GNUism, though.
Traditionally the a(ppend) command is spelled like this:
[1addr]a\
text
to write one line (cf. http://pubs.opengroup.org/onlinepubs/9699919799/utilities/sed.html#tag_20_116_13_03).
Why is "pick" special? Don't you want to run the commands after
"edit", "reword", "squash", "fixup"?
This should come immediately after autosquash rearranged the insns
in the $todo file, before the help text is appended to it.

You copied badness from the existing "unset onto"; I do not think
the rest of the code (and especially the new code you add) treats a
variable that is not set and set to an empty string any different,
and setting it to empty is the right thing to do in such a case.

exec_flag is not cleared at the beginning of the script, so if the
command is run without "-x" on the command line, it can have
whatever garbage value that was in the environment. You know that
$cmd is empty if "-x" was not given, and you can make sure $cmd
becomes non-empty when "-x" is given, so remove use of this variable
and replace any 'test -n "$exec_flag"' with 'test -n "$cmd"'.

Why 3? You only care about the presense of $2 you are about to
read, no?

Are you telling me that I cannot have a branch named "make"? Drop
this nonsense, and just write it in a more straightforward way, e.g.
-x)
test 2 -le "$#" || usage
cmd="${cmd:+"$cmd$LF"} $2"
