Re: [Technical Errata Reported] RFC7230 (4189)

Another question about obs-fold before we proceed with the formal
definitions. Consider the following example

foo: bar<CRLF>
<SP><CRLF>
...

It won't be surprising if some parser mistakes the 2nd line as an
"empty line" that terminates the headers. Visually it *is* an empty
line.

In spirit, obs-fold should be followed by visible chars, otherwise
it's very confusing and problematic.

RFC 822 $3.2 appears to suggest the same thing, that obs-fold can only
appear between two non-empty segments.
