=3D may be the common one, but =20 and =09 are others that end up
showing up when whitespace gets quoted for various reasons.

Another one is =46 for 'F'. Why? Because some mailers think that
"From" at the beginning of a line is the mbox beginning marker, and
they'll escape any line that begins with "From" to use "=46rom"
instead.

Those mailers are wrong (at a _minimum_ it's "From " with a space, and
you generally should be even stricter than that), but it happens.

And obviously, if there is real 8-bit stuff, you'll get all the real
odd hex noise.
