"patch" in html version of spec

[Roger Light <roger@atchoo.org>]

Hello,

The html version of the 3.1.1 with errata 01 spec has an error in the
remaining length calculation pseudo code. It looks as though the html
document was generated from the .doc with track changes enabled, so
there is the old and new versions both present.

Cheers,
