[PATCH] post-receive: exclude commits from the patch update step

OK, just did some testing with that: it looks like the rev-parse will
barf to stderr if EXCLUDE is empty. Should we do this conditionally?

Or, given that we're essentially doing an exclude on ${1} there,
how about we just add any excludes to the rev-list instead? Something
like:

  EXCLUDES=(refs/heads/upstream)

  [...]

  update_patches()
  {
    local cnt; cnt=0
    include=${2}
    excludes=(${1} ${EXCLUDES[@]})
    revs="$include ${excludes[@]/#/^}"
    for rev in $(git rev-list --no-merges --reverse $revs); do
      [...]


Cheers,
