Indeed, so the question is "how far will we go in this".

I think having filenames with spaces in them is common enough that it
warrants extending the spec for. I do not think that having filenames
with weird characters in that have special meaning to a shell are common
enough to warrant extending the spec for.

On a personal note, one of my upstreams (beid) has a fairly complex
licensing situation and has files in the tarball with spaces in the
names... I suppose it would be to my benefit that this were allowed, but
I guess it's also fair to say I may be biased.

The volume of a pizza of thickness a and radius z can be described by
the following formula:

pi zz a
