This is actually not a WinIgc coding, but a quoted-printable encoding
used in emails. It looks like your email program (or some other program)
didn't handle the SGF correctly and you got the "raw" email text of the
SGF encoded in quoted-printable.
More information see RFC1521 at e.g.
Speaking from my experience such SGF files appear every once in a while
(usually happens while forwarding emails, posting to newsgroups, or
saving the email instead of the SGF attachment).
