My response here is probably OT, but RFC 822 is the only RFC that talks
about folding by *inserting* whitespace. both RFC 2822 and RFC 5322
say folding is done by inserting <CRLF> ahead of *existing* whitespace
and unfolding is done by removing the <CRLF> (only). Thus, the
question of whether folding was with <tab> or <space> should not arise.

Of course, in terms of trying to reconstruct the original on_the_wire
message exactly, the question of where the folding occurred is still
relevant. but if we're doing the right thing, the question of what
character should follow the <CRLF> is not.
