[Message part 1 (text/plain, inline)]

Juanma, thank you for the lisp code that reproduces the same problem that I
am having.

If a space is inserted at the beginning of the buffer, then the result is
correct (as stated in my bug report):

(with-temp-buffer
 (insert " ")
 (insert (make-string 20 ?.))
 (decode-coding-region 2 (point-max) 'us-ascii)
 (buffer-string))
" ...................."

(I use 'us-ascii just to show the coding does not matter).

Now, hopefully emacs developers will  be able to understand and fix the
problem.
