Please, find attached a new version of the patch.

It contains the following changes:

- Add a new function named `fill-region-as-paragraph-semlf', which fills
  a region using semantic linefeeds as if it were a single paragraph.
  Its behavior is analogous to `fill-region-as-paragraph'.
- Update the `fill-paragraph-semlf' function to use
  `fill-region-as-paragraph-semlf' internally.
- Remove the mention about using `fill-paragraph-semlf' as
  `fill-paragraph-function' from docs, given that the long term plan is
  to obsolete this.
- Add test for `fill-region-as-paragraph-semlf'.

Thanks a lot for all the explanations.  I hope this new version is
closer to what you had in mind.
