Using waf.bat on Windows (7) could lead to %PYTHON% not set correctly

[bcamel]

There seems to be a small issue in waf.bat
In line 46:

set REG_PYTHON=!REG_PYTHON_DIR!!REG_PYTHON_EXE!

the path separator between REG_PYTHON_DIR and REG_PYTHON_EXE is missing, leading to potential issues like:

Find C:\Anaconda2python.exe
Using C:\Anaconda2python.exe
'"C:\Anaconda2python.exe"' is not recognized as an internal or external command,
operable program or batch file.

I suggest to just change line 46 to:

set REG_PYTHON=!REG_PYTHON_DIR!\!REG_PYTHON_EXE!
