Re: [netmod] New Version Notification for draft-kwatsen-netmod-artwork-folding-07.txt

Yeah :-Z

So my inclination is to say "tabs in artwork are evil" and move on.
Some folk like to use them when constructing text, but my suggestion is that they convert to spaces/LF before posting drafts.

If anyone wants to write another document tabs in json then, erm, knock yourselves out. But I would prefer to just exclude them from folding at this time.

Cheers,
Adrian
