AFAIK, the first whitespace character after the newline should be
discarded, because it is the functional whitespace. In this way you
can have a break inside long strings without any embedded whitespace.
RFC2822 only allows for folding a header line where there is whitespace,
so a long string cannot be folded in the middle:
"For convenience however, and to deal with the 998/78 character
limitations per line, the field body portion of a header field can be
split into a multiple line representation; this is called "folding".
The general rule is that wherever this standard allows for folding
white space (not simply WSP characters), a CRLF may be inserted before
any WSP."
