[C++-sig] Pyste support for include paths with spaces

[paul.bridger]

Currently Pyste/GCCXML has a problem with spaces in include paths.

My command-line:
pyste.py -I "C:\Program Files\Microsoft Visual Studio .NET 
2003\Vc7\include" StdString.pyste

My .pyste file:
string = Class('std::string', 'string')

(Please try to imagine for a moment that I have a valid reason to be 
wrapping std::string).

With an unpatched Pyste, this has the problem that when
"C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\include\string" 
is found and passed to GCCXML for parsing, GCCXML interprets this as 
multiple files separated by spaces:
C:\Program
Files\Microsoft
Visual
Studio
..., you get the idea.
GCCXML doesn't like it.

CppParser.py:114, unmodified:
cmd = 'gccxml %s %s %s -fxml=%s

CppParser.py:114, with my fix:
cmd = 'gccxml %s %s "%s" -fxml=%s
