[O] Incorrect hexification in URLs in LaTeX Export

[R. Michael Weylandt <address@hidden>]

I've tried this with Org 7.9.3 and 8.2.5h to the same result:

<---------------------->
#+TITLE: Test
* One
Here is a [[http://google.com/search?q=orgmode][link]]
<---------------------->

Exporting to HTML doesn't transform the link but exporting to LaTeX results in 
the (non-working) http://google.com/search?%3Dorgmode

Is there a reason for this behavior and, if so, a way to work around it?

RFC 3986 2.2 explicitly says URLs may include `=` and =url-encode-url= doesn't 
change the link in question.

I've played with org-url-hexify-p and read past ML discussions, but they seem 
primarily concerned with characters which should not appear in URIs. 

Thanks,
Michael
