[PATCH] Pipes for win32 vim

[Vincent Berthoux]

Hello,

This patch implement a pipe mechanism for the Win32 version of vim,
it's benefits are :
- No more temporary files for filtering
- No console window opening while launching a shell command
- Command results are directly displayed in the GVim window.
With this patch, gvim behave the same way as gvim in Linux/Mac OS with
regard to the shell.

Tested on : Windows7 x64 - GVim

One reason to use a console is that some programs don't work without
one. In rare cases it may cause the system to crash. I'm not sure how
often this still happens with the check that you included, but perhaps
it also requires an option so that the user can switch off pipes when
they are not wanted? Either globally or something that can be selected
per command.

Hmm I didn't think about it, but I think I can do something by using
the 'shelltemp' option, as the meaning more or less match the use of
pipe, if we don't use pipes. We can show the command window as usual
if 'shelltemp' is off, this way remaining backward compatible with the
current behavior.

I'm going to investigate and send an updated patch

Here is the updated patch with the fallback to the old behavior if shelltemp is
set to true.
