MAPINFO : 'GetStyleString' returns dot delimited id list

[dev@…]

The style string returned by 'GetStyleString' for Mapinfo files
contains pens, brushes and symbols ids separated by dots instead
of commas.
For example :
       PEN(id:"mapinfo-pen-14.ogr-pen-6")
should be
       PEN(id:"mapinfo-pen-14,ogr-pen-6")

The error is located in mitab_feature.cpp in GetPenStyleString, 
GetBrushStyleString and GetSymbolStyleString.
