[PATCH] mailinfo: handle folded header.

[PATCH] mailinfo: handle folded header.

Some people split their long E-mail address over two lines
using the RFC2822 header "folding".  We can lose authorship
information this way, so make a minimum effort to deal with it,
instead of special casing only the "Subject:" field.

We could teach mailsplit to unfold the folded header, but
teaching mailinfo about folding would make more sense; a single
message can be fed to mailinfo without going through mailsplit.
