Subject: [PATCH] New shebangs script; fixes to tar utilities and hugo-post
 script

The shebangs script helps me manage dependency listings.

The tar utilities were failing with to-directory options or passphrase
options containing space characters. The fix requires some unappealing
bash-isms, but at least it works.

hugo-post now will work from the root directory of a Hugo project.
