No, that's not what I meant. There is no point in making "git show" to
have no output by default, please see below.

My point is that the default format should be selected as if it has been
provided by existing options, rather than by some magic hidden in the
code.

That's not what I had in mind, sorry. It'd rather be something like:
--raw: set "raw" bit and clear all the rest
--+raw set "raw" bit (== current --raw)
---raw clear "raw" bit (== --no-raw)
In this model
git show
would be just an alias for
git log -n1 --patch --cc
and no support for a separate command would be need in the first place.
git show --raw
would then produce expected output that makes sense due to the common
option processing rules, not because somebody had implemented some
arbitrary "defaults" for the command.
Then one can even think about supporting some niceties like
git log --patch+raw
In other words, if we provide full orthogonal access to (the diff
output) bits using CL options, no special code wold be ever needed to
implement some niceties and shortcuts.
Disclaimer: please keep this with a grain of salt as this is not a
carefully thought-through proposal. Not yet anyway. Just me thinking
aloud.
For *nix guys, the closest analogy to the above is probably:
chmod og-wx
