Currently, "diff" and "cat-file" for blobs honor "--textconv" options
(with the former defaulting to "--textconv" and the latter to
"--no-textconv") whereas "show" does not honor this option, even though
it takes diff options.
Make "show" on blobs behave like "diff", i.e. honor "--textconv" by
default and "--no-textconv" when given.
