Teaser Break doesn't work

hi,

it appears that the teaser break code is getting "adjusted" and hence fails to work.

what happens is:
1. enter teaser break:

2. save
3. return to edit mode, look at underlying code, and the break has changed to:

(notice the two spaces around the word 'break' that have been inserted. i think that kills it.)

i'm loving XStandard, and thanks for running w/ this.

best,
