[Emacs-diffs] master 08aa6a0: Improve and make use of 'image--get-image'

[Charles A. Roelli]

branch: master
commit 08aa6a0533c44771fb8c43771d806d3bf6ac3776
Author: Charles A. Roelli <address@hidden>
Commit: Charles A. Roelli <address@hidden>

    Improve and make use of 'image--get-image'
    
    * lisp/image.el (image--get-image): Add documentation, and
    check overlays for images too (since function 'put-image' from
    the same library uses overlays to insert images).
    (image-save): Use 'image--get-image'.
