Re: [PATCH] ob-maxima.el: Fix execution on MS Windows

[Max Nikulin]

Nikolay, I do not have any objections concerning the last version of 
your patch (I have not test it though). It is tracked on 
https://updates.orgmode.org/ however it may take months before it will 
be committed.

Have you signed FSF papers related to copyright? See 
https://orgmode.org/worg/org-contribute.html#copyright There is no 
"TINYCHANGE" keyword in the commit message and I have not found you in 
the list of contributors to Org mode (Bastien likely have access to more 
actual data). Since several your patches have been accepted to Emacs, 
you are close to the limit when formalities become necessary.

Do not consider the comments below as a request to change anything in 
the patch. I am just trying to express more clear what I wrote in the 
previous message.

Consider a really peculiar path for tmp files with quotes

     /tmp/")$ something-weird$ "/maxima-ua3e9j.max

I hope, it is unrealistic and will be properly escaped by %S formatter. 
I am a bit surprised that Maxima does not allow to do it in a more 
reliable way since several interfaces exist (WxMaxima, texmacs). Unsure 
if get_application_args is suitable

It would be great if it had another flag to suppress printing content of 
the batch script or a flag that changes a setting that controls such 
behavior.
