t-vim module quoting problem on OS X

t-vim module quoting problem on OS X

[Riobard]

Hi,

t-vim.tex has a very strange quoting issue when it tries to invoke
vim. Here is the piece of code that causes problem:

----------------------
\def\runvimsyntax#1
   {\executesystemcommand
      {mtxrun --verbose --noquote bin:vim
          "-u NONE  % No need to read unnessary configurations
           -e       % run in ex mode
           -C       % Set compatibile
           -n       % No swap
%          -V10log  % For debugging only, will go away later.
           -c \shellescapedquote set tabstop=\@@vstab
\shellescapedquote\space
           -c \shellescapedquote syntax on\shellescapedquote\space
           -c \shellescapedquote set syntax=\@@vssyntax\shellescapedquote\space
           -c \shellescapedquote let
contextstartline=\@@vsstart\shellescapedquote\space
           -c \shellescapedquote let
contextstopline=\@@vsstop\shellescapedquote  \space
           -c \shellescapedquote source
kpse:2context.vim\shellescapedquote\space
           -c \shellescapedquote wqa\shellescapedquote\space
            \shellescapedquote#1\shellescapedquote\space " }}
-------------------------

On OS X (10.6) Vim complains:

VIM - Vi IMproved 7.2 (2008 Aug 9, compiled Feb 10 2010 21:54:21)
Garbage after option argument: "-u NONE -e -C -n -c "set tabstop=8" -c
"syntax on" -c "set syntax=scala" -c "let contextstartline=1" -c "let
contextstopline=0" -c "source
/Users/rio/ConTeXt/tex/texmf-context/tex/context/third/vim/2context.vim"
-c "wqa" "usecase-vimsyntax.tmp" "
More info with: "vim -h"

I searched the mailing list and found an old thread where Mojca talked
about the rare strange quoting behavior. So I changed the above code
to

--------------------------
\def\runvimsyntax#1
   {\executesystemcommand
      {mtxrun --verbose --noquote bin:vim
           -u NONE  % No need to read unnessary configurations
           -e       % run in ex mode
           -C       % Set compatibile
           -n       % No swap
%          -V10log  % For debugging only, will go away later.
           -c "set tabstop=\@@vstab"
           -c "syntax on"
           -c "set syntax=\@@vssyntax"
           -c "let contextstartline=\@@vsstart"
           -c "let contextstopline=\@@vsstop"
           -c "source kpse:2context.vim"
           -c "wqa"
            "#1"}}
-----------------------------

and it works on OS X. Not sure if it will work on other platforms. Can
someone try it out on Windows and Linux please? What's the proper way
to do quoting in a crossplatform manner in ConTeXt?
