Org file looks like following:

  * heading
    my line.

  when cursor is at beginning of file, `org-forward-sentence' goes to the end of "my line.", which does not seem to be correct (heading is special outline). Then calling `org-backward-sentence' behaves correctly, ie it goes to the beginning of "my line.".

  To workaround the problem I kept on inserting dot at the end of each heading. Until yesterday where I wanted to add link to heading from another file. When dot is at the end of heading, then adding dot to the end of link does not work.

  file:./fil.org::heading.
 
  correct behavior of `org-forward-sentence' would probably fix the problem, ie I could remove dots from ends of all the headings
