This small patch fixes the bug #17555. This increases the consistency
of `mark-paragraph` with `mark-word` and `mark-sexp`.

Currently "C-- M-h M-h" will end up selecting nothing since repeating
`mark-paragraph` always expands forwards even if `mark-paragraph` was
initially invoked with a negative prefix argument.

This is my first patch to Emacs. I have not signed the papers
assigning copyright to FSF. I would like to do so but I cannot figure
out how to.

Kind regards
Simon Friis Vindum

I haven't got a chance to look at your patch. But can share my experience
about copyright assignment :)

Here are the steps I took and the process was smooth:
- Email FSF at assign@gnu.org requesting to initiate the copyright
assignment process.
- They will send you a 4 or 5 question questionnaire by email.
- You reply that via email.
- Then you get a format of disclosure that needs to be signed by your
school or employer.
- I did not face any problem there, the employer sent me the signed letter
in pdf form in 2 days.
- I was supposed to snail mail the physical signed copy to FSF but I didn't
have one and they were fine with the scanned signed letter pdf I emailed
them. I believe that is fine in US. But the person responding to you from
assign@gnu.org will guide you correctly.
- Done!

It took a couple of days, but it was all email transactions for me.
