[Request Tracker]

this bug's URL: http://intevation.de/rt/webrt?serial_num=2152
-------------------------------------------------------------------------

Subject: VRML 1.0 export

Platform: other (dual-G4 / MacOSX 2)
grass obtained from: Other (CDROM etc) (OpenOSX)
grass binary for platform: Downloaded precompiled Binaries
GRASS Version: 5.0.2

The VRML 1.0 export is not working well. The mesh producted is not standard VRML. It 
adds a ' , ' after the last Coordinate3 point description. Same for the last 
IndexedFaceSet : should be "a,b,c,-1"  and not "a,b,c,-1,"
