bug#17867: 24.3.90; Printing of overlayed text not reagarding overlays anymore

[Stefan-W. Hahn]

Good morning,

I'm using emacs heavily with org-mode on windows and be used
to print parts of org-mode files from within emacs as postscript.

With the change

|     * src/buffer.c (Foverlays_at): Add argument `sorted'.
|     * doc/lispref/display.texi (Overlay Properties): Reword the doc of `priority'.
|     (Finding Overlays): Document new arg of `overlays-at'.
|     * lisp/obsolete/lucid.el (extent-at):
|     * lisp/htmlfontify.el (hfy-overlay-props-at): Use the new `sorted' arg of
|     overlays-at.
|     (hfy-fontify-buffer): Remove unused var `orig-ovls'.
|     * lisp/ps-def.el (ps-generate-postscript-with-faces1): Use the new `sorted'
|     arg of overlays-at.  Use `invisible-p'.
`----

in lisp/ps-def.el the interpretation of overlays was removed.

Example:
In org-mode you can have links like this

   [[file:private.org][My special file]]

this is overlayed and you see (in emacs)

   My special file

with face.

Before the mentioned change this will be printed also in this way. After the
change it will be printed as in the shown in the first line

This means that printing org-mode tables is not fulfilling anymore.

Is there anything I misunterstood? Perhaps another possibility to
print overlayed text? If not I think this is a bug.

With kind regards
Stefan

Indeed, thanks.  I installed the patch below which seems to fix
the problem.
