[GRASS-windows] Forward slash / back slash in r.out.xyz

[Peter Brooks]

Using GRASS 6.4.0SVN and the Python GUI. 

(Sorry don't know if this has been fixed in a later version, is a 
known bug or happens in other routines).

Exporting from raster (r.out.xyz)

Using the 'Browse' function for 'Name for output file' ('Optional' 
tab) returns the folder path with Windows style back slashes.

Running the routine the export file doesn't appear in the folder path 
(don't know where it is written to).

Changing the back slashes to unix style forward slashes works and the 
file is exported to the folder as expected.

Hope this helps anyone else mystified by this!

Cheers
Peter
