hi,

i found this behavior while using auctex. to recreate, create a new
buffer for a tex document, with auctex as the mode (LaTeX-mode). type
in the first line 'this is a test'.

go down one line. '(point)' should return 16. now evaluate
'(save-excursion (LaTeX-fill-region-as-paragraph 1 16 t))'. nothing
actually changes in the buffer, but the cursor jumps to point 15. you
can repeat this with the same results.

can someone please tell me what is going on? also, if i write a
function that uses LaTeX-fill-region-as-paragraph, how can i return
the cursor to its original place (i'm currently using markers,
however, putting the cursor inside the filled region  creates weird
behaviors)

thanx,
ittay
