Re: Patch to avoid superfluous output directories

[Al Haji-Ali]

Hello Ikumi,

Apologies for the late reply. I've been somewhat busy these days.

I enable TeX-source-correlate-mode in LaTeX-mode-hook. Then I get the following 
calls when I open a tex file:

TeX-source-correlate-mode -> TeX-set-mode-name -> TeX-region-file

(Below is the complete call stack starting from `find-file-noselect`). This 
happens before local variables are hacked (like TeX-master). In my case since 
`TeX-output-dir` is set to non-nil (globally) then `TeX-region-file` calls 
`TeX--master-output-dir` which creates an output directory if it does not exist 
(without the patch I emailed earlier). Since `TeX-master` is not set correctly 
the output directory might be created in the wrong location,

Let me know if you need more info.
