fixedsync.mdwn: change sync from v3.1B version to v3.0B version

to use the v3.1B version requires fixing fields.text to use the new
L and SC fields, which requires deciphering all the places where the
current L (named L2) field is used and making sure they'll be correct still.

using the old interpretation of sync should be correct, but less optimal,
assuming OpenPower got their backwards compatibility correct.
