This bug is being looked into. It only affects tty font-lock settings
within a .emacs file. If you do not use color syntaxing in Emacs under
an xterm, this will not affect you. For those that do, setting TERM
to xterm (rather then one of the color xterm variants) is a temporary
fix.
Some of you may opt to stick with 20.x, as this is a typical beginning of
a major rev. Maintainership is directed my way, so feed patches to me.
Thanks to A B <obsdfaq30@yahoo.com> for the submission.
