Add some new options to aid scripted calls to git-publish

[stsquad]

So much of my workflow is in emacs org-mode that I want to better support scripted calls to git-publish. After modernising the options parsing code I add a few new options to support that.

For an example my org file now looks like this:

*** Publish the results
:PROPERTIES:
:header-args+: :var tree="" :var base=""
:END:

We need to force the :dir for our find-unreviewed-patches call for some reason

#+name: git-publish-prepare
#+header: :results output
#+header: :var needs_review=find-unreviewed-patches-elisp[:dir /home/alex/lsrc/qemu.git]()
#+begin_src sh :async
  branch=$(git symbolic-ref --short HEAD)
  base=${revspec%%..*}
  echo "Working on $branch, based off $base in $PWD"
  # with prefix reset everything
  if test -n "$prefix"; then
      git tag -d ${branch}-staging
  fi
  git tag -l --format="%(contents)" ${branch}-staging > ${branch}.cover
  # Cut any old needs review data?
  lines=$(grep -n "The following patches need review" ${branch}.cover | cut -f1 -d: | head -n1)
  if test -n "${lines}"; then
     keep=$(expr ${lines} - 1)
     echo "Stripping everything after ${keep}"
     head -n $keep ${branch}.cover > ${branch}.cover.tmp
     mv ${branch}.cover.tmp ${branch}.cover
  fi
  # Add needs review to the cover letter
  echo "" >> ${branch}.cover
  echo "The following patches need review:" >> ${branch}.cover
  echo "" >> ${branch}.cover
  echo "${needs_review}" >> ${branch}.cover
  git tag -f -F ${branch}.cover ${branch}-staging
  echo $EDITOR
  git-publish --base ${base} --edit
#+end_src

#+RESULTS: git-publish-prepare
: Working on gdbstub/next, based off origin/master in /home/alex/lsrc/qemu.git
: Stripping everything after 5
: Updated tag 'gdbstub/next-staging' (was e8dcee1e46)
: emacsclient -a ''
: Waiting for Emacs...
