[O] Some links not working anymore for me

[François Pinard]

Hi, Org people.

For a little while, I've not been able to follow links to Org files,
when the link contains a search to some header, and the searched header
itself contains white space or non-ASCII characters.  I just made this
patch that apparently helps me out of this new little misery :-).  The
patch is only indicative: I'm not sure it is the proper way to solve the
difficulty, as I do not really understand all the code surrounding it!
