There are still firm objections against enabling `TeX-parse-self' by
default.  You can read discussion about this, e.g., at the thread
beginning with
https://lists.gnu.org/archive/html/auctex-devel/2017-02/msg00000.html

Thank you very much for this helpful information!  Now I understand that the reason for the objection is that if the variable is set to t,

AUCTeX [would] rifle through whole remote directory hierarchies in the search for style files.  [This is a quote from David Kastrup.]

What I don't understand is how this is related to the percent symbol in URLs !

Also, I didn't notice any slow down even after setting the variable to t.  (I actually expected it, because "parse" sounds a time consuming operation.)

Following his advice, I looked at the top of the AUCtex manual and found:

If you want to make AUCTEX aware of style files and multi-file documents right away, insert the following in your .emacs file.
. . . .
(setq TeX-parse-self t)
. . . .

I still don't see how this is related to URLs . . . 

I'm not complaining.  Not at all.  It just shows how hard it is to find the  information I wanted.

So, even though Arash says

but it seems to me that users start asking google instead of reading the first 5 paragraphs of the manual

in the thread above, you shouldn't blame the users (like me) :-)

Cheers,
Ryo
