Okay, I could reproduce it with Emacs 21.3.  This is actually a very
severe bug.  After the paragraph to be filled _every_ sentence ending
at the end of a line will get an extra space.  It would be good to
release 11.55 in the near future.

I fixed it in CVS.  A patch against 11.54 is attached.

Daniel, thanks for the report.
