(Manual behavior):
If pwd is WORKTREE/ then git-checkout has correct effect, ie. worktree, 
index, and HEAD match.
If pwd is WORKTREE/.git/ then git-checkout complains 'must be run in a 
worktree' and has no effect.

(post-update hook behavior):
If pwd is WORKTREE/.git/ then git-push verbage does not complain, and 
git-checkout exits zero status but has incorrect effect, ie. index and 
HEAD match, but worktree matches HEAD@{1}.
If pwd is WORKTREE/ then git-push complains 'not a git repository', and 
git-checkout exits non-zero status and has no effect, ie. worktree and 
index match HEAD@{1}.

Evidence:

(post-update hook script):
MYPWD=`pwd`
echo $MYPWD
pushd /home/neal/FSNMSTHTML
MYPWD=`pwd`
echo $MYPWD
git checkout -f HEAD
if [ $? -ne 0 ]; then
   echo "error on checkout!"
else
   echo "checkout HEAD to non-bare remote current branch after push"
fi
echo $MYPWD
popd
MYPWD=`pwd`
echo $MYPWD

(git-push verbage):
$ git push origin HEAD
