[O] Fill-mode not working when lines start with *bold* word

[John Hendy]

I have the following fill-mode related settings:

(setq-default fill-column 90)
(add-hook 'text-mode-hook 'turn-on-auto-fill)

I just noticed this behavior the other day when adding a note for a report:

#+begin_src org
Note: this line, starting with a plain vanilla word will wrap just
fine. It will not go
on and on and on and on.

/Note:/ this line, starting with a word in italics markup will wrap
just fine. It will
not go on and on and on.

*Note:* this line, starting with a word in bold markup will not wrap
just fine. It will go on and on and on.
#+end_src

I'm not sure if this has always been the case or if a change affected
some behavior. It strikes me that I would have used this notation
before and I never noticed this, so my intuition is that it's a
change-related issue.

Let me know if I should check other config options that might be
causing this. I could post a link to a paste-bin of my .emacs if that
would help diagnose.


Thanks,
John
