[Message part 1 (text/plain, inline)]

Hi!

I am sorry if this is the wrong place to report this but:

When editing in LaTeX mode in Emacs, if an href link has a percent sign, 
it will display the rest of the line as if it were a comment.
Everything still "compiles" correctly, but in terms of the "visual 
effect", it is wrong, since percent signs in the link should not give 
the impression of "commenting out" the rest of the line.
Here is an example:

This is what actually happens:
*\href{https://en.wikipedia.org/wiki/Wigner%E2%80%93Seitz_cell}{Wigner-Seitz 
cell}*

This is how it should be:
*\href{https://en.wikipedia.org/wiki/Wigner%E2%80%93Seitz_cell}{Wigner-Seitz 
cell}*

Could someone forward this report/query to the right location...
(Also, in case it's relevant I'm using Emacs 25.2.2 on Ubuntu 18.04.2 
GNU/Linux.)

Best,
/Nathan

Hi Nathan,

I presume you're using AUCTeX.  In that case, the correct list is
bug-auctex <at> gnu.org.

Thanks for catching this.  I've added to patch to hyperref.el fixing
this issue[1].  As an intermediate solution, you can add the following
lines to your init file until the next release of AUCTeX:

    (with-eval-after-load "hyperref"
      (add-to-list 'LaTeX-verbatim-macros-with-braces-local "href")
      (font-latex-update-font-lock t))

Best, Arash

Following up myself, this was an AUCTeX issue which is resolved.  Hence
I'm closing this report.

Best, Arash
