I think curly makes the most sense for grouping, though I still think it
is a bit ugly. Patch is below.

Subject: [PATCH] fix cat-file usage message and documentation
cat-file with an object on the command line requires an
option to tell it what to output (type, size, pretty-print,
etc). However, the square brackets in the usage imply that
those options are not required. This patch switches them to
curly braces to indicate "required but grouped-OR".
While we're at it, let's change the <sha1> specifier in the
usage to <object>. That's what the documentation uses, and
it does actually use the regular object lookup.
---
The curly braces seem to render fine via asciidoc (presumably because
there is no entity with that name), but I'm not sure if that will work
with all asciidoc versions.
