Right, I had to run your script with chmod +x directly so that it
actually works locally. Silly me trying to do 'sh'.

Right. So I ran it and saw you had a conflict. Now looking at this
article (after a quick googling) :
-- it explains one way of doing it. Basically you rebase first before
you merge (which works for the case you point out).

Attached is the script that is modified to address the specific issue you raise.


PS. Of course this only makes sense on repositories you actually
control -- i.e. locally. If you're tracking a remote branch, this
could screw up your local branch -- in those cases it's best that you
actually have a branch from the remote tracking branch and rebase that
before you actually merge back into the "main" branch from which the
remote tracking branch is forked off. Your branch and the remote
branch can diverge (which actually happens quite a bit with git) but
with proper re-alignment procedures -- i.e. pulling or making sure
your changes are upstream -- these things can largely be avoided.
