Makes sense.

The shell should know, after seeing $FILE_WITH_COMMIT_MESSAGE and
encountering the end of line, that you haven't completed telling
what you started telling it.  Do you need " \" at the end of the
line?

I know that it was suggested to use a file with message, and I agree
with the suggestion, but then I wonder if we want to be more
complete and show that a file gets prepared in the example to avoid
making readers wonder where $FILE_WITH_COMMIT_MESSAGE comes from?

E.g.,

        vi message.txt
        NEWCOMMIT=$(git comimt-tree $NEWTREE -F message.txt
                    -p $BRANCH1 -p $BRANCH2)

or something like that?

Other than that, looking good.

Thanks.
