Re: [PATCH 0/2] cat-file: support NUL-delimited input with `-z`

This short patch series implements a `-z` mode that is compatible with
the `--batch`, `--batch-check`, and new `--batch-command` options in
`cat-file`.

It's a shame that we forgot that people use strange "object name"
like "<tree>:<path>", when we originally intended to only take
simple object names, like fully-spelled hexadecimal.  And if we were
prepared to take <path>, we should have make sure we use the usual
cquote convention.
