* org-mode pretty entities has \perp but not \parallel

Hi, I expected \parallel to work after success with \perp. That is, I've executed in buffer M-x org-toggle-pretty-entities RET, and I expected to see \parallel as unicode ∥, since \perp is overlayed (correct term?) with ⟂. Though, the former is pretty hard to see, so maybe it was decided against.

I just tried exporting to HTML (and MathJax), and it looks like the LaTeX delimited symbols should be either $\parallel$ or $\|$. So simply writing $||$ in ones' notes would /not/ be the same.

\parallel should be added IMO as it's supported by vanilla LaTeX.

Would you be interested in providing a patch?  You would have to add it
to org-entities.el, e.g. after the perp entity and then send the patch
to this list.

Maybe you don't have a good font?  My Emacs picks it up from Biolinum.

I think this works, I did try it, with M-x org-toggle-pretty-entities. (Re: 5th and 6th argument: Is "||" a good ASCII/Latin1 representation?) 

#+BEGIN_SRC emacs-lisp
("parallel" "\\parallel" t "&parallel;" "||" "||" "∥")
#+END_SRC

I also tried to add something like

#+BEGIN_SRC 
("|" "\\\|" t "&parallel;" "||" "||" "∥")
#+END_SRC

with "\\\|" or "\\|", but it wasn't working for me. I didn't see any non-alphabetical entities ("name") in the variable org-entities-user, so I was guessing it wouldn't work with a one-line edit. 

Is the patch okay? I simply used C-x s d (C-g C-x b *Diff* RET).

Except the ∥ that was somehow eaten in your snip (but OK below).

I think they are not the same.  I'd use $\|x\|_2$ for a norm, say.
Parallel is a relation: $a\parallel b$.

If you want to go "all in", which is a lot of fun, you have to submit a
TINY PATCH:

     http://orgmode.org/worg/org-contribute.html

Otherwise, I'm happy to submit it for you (though I'm not sure if
something like this would go to maint or master...?)

Hmm, not sure where that happened, I'll have to look out for that when I'm emailing unicode parallel lines again. :)

Ah yes. Now this \| makes more sense.

Yes please do submit when you have the time, though I will try to get closer to being setup for this when I can. (E.g., I'm currently on Elpa Org-mode... and my commits are mostly linear for personal files.)

Pushed.

My "work Org" (is /usr/share/emacs/site-lisp) is different from my
"develop Org" checkout (in ~/src/org-mode), though both are based on
master.

Feel free to come back and contribute some more later!
