bug#9178: 23.1; iimage mode copy and paste file corruption

[Jason Baietto <jason@cholula.ccur.com>]

I am using the iimage mode to display in-lined images in text files.
When images are displayed, an image may be double-clicked to select
it and then pasted at point within the same buffer using the middle
mouse button.  I can do this using emacs on both Linux and Windows.

The image will appear to be inserted at point and will be displayed as
as expected (i.e. as a picture).  However, the the copy and paste was
a lie.  Although the image is displayed at the new location, only the
first selectable "word" of the image path has been selected and
pasted.  The file has now been corrupted, and if you now delete the
original image path the image path will be lost; upon the next visit
to the file only the first word that was pasted will be displayed.
