[AUCTeX] Merge pdfclose into auctex workflow

[Jiajin Yu]

Hi,

I want to avoid the "lock" problem in acrobat reader in Windows
platform. One way to do this is to use pdfopen/pdfclose tools (if
using MiKTeX, they're already there). The solution is when Emacs open
a pdf file to preview, it invokes "pdfopen", and when it needs to
compile the latex source to pdf again, it first invoke "pdfclose",
then called the standard procedure.

I know I can use TeX-output-view-style to customize the view
procedure, but how can I insert command "pdfclose" before the standard
compiling procedure with minimal change of the original ones?


Thanks,
Jiajin
