To the GNU bug tracker, debbugs.gnu.org, assigned to the package auctex.

Me neither. :-)

The reason is that once the auto-parser has kicked in and seen that you
are using the hyperref LaTeX package, it'll recognize the \href macro
(which is now also fontified correctly, e.g., not with
font-lock-comment-face including and after the first %) and know that
the % in the URL are not starting a comment.

To demonstrate: When you comment the \usepackage{hyperref} and hit `C-c
C-n' the problem will be back.  Uncommenting it again then and hitting
`C-c C-n' makes it disappear.

Bye the way, you might want to add

    (setq TeX-parse-self t)
    (setq TeX-auto-save t)

to your auctex config as described in (info "(auctex) Top").

Bye,
