[O] ATTR_LATEX :options ignored for source code

[Jeff Trull]

According to the manual users can supply #+ATTR_LATEX: :options ... prior
to a source section and the options present will be supplied to the
environment (lstlistings in my case).  I find that this does not work -
regardless of settings, no options are supplied to the lstlistings
environment.  Attached is a test case that demonstrates the problem.  It is
taken from the manual.

I have found the other problem, the below two version of
org-create-formula-image-with-dvipng generate different size png,

Then is :scale 1.2 enough?

If it is too ugly, it will also force users configuring it anyway.

The problem is that the pic is too small and nearly can not see the words in 
the picture, it will force user config it, if we use a larger pic, it can work 
although it is ugly

As a data point, I use :scale 1.2. A factor of 2 may be too large for
some users.

In any case, the manual already highlights it:

 You can customize the variable ‘org-format-latex-options’ to
  influence some aspects of the preview.  In particular, the ‘:scale’ (and
  for HTML export, ‘:html-scale’) property can be used to adjust the size
  of the preview images.

Since there may not be a more reasonable default value, the best thing
to do could be to leave it up to the user to set his own factor.

WDYT?

As Eric said, this bug was fixed a while ago. Basically, the solution
was to replace `completing-read' with `org-completing-read'. At the
moment, "org-capture.el" calls the latter (see line 1765 from master
branch).

You may want to check why `completing-read' is called instead in your
configuration.

FWIW, I cannot reproduce the problem. You may want to edebug

You could cheat and prefix your variable with "org-", e.g.,
"org-modi/...".

You could also try removing the limitation in the code I quoted earlier
so that it really copies all local variables before the export process,
and test if there are some drawbacks to it.
