show: honor --textconv for blobs

Browse source 
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 honor "--textconv" when it is asked.  The default
is not to apply textconv, which is in line with what "cat-file" does.
