VLM export syntax error

To reproduce, create a new vlm entry, select output, click on option, next, next and check some checkboxe. It will produce something like :

:sout=#transcode{vcodec=h264,vb=0,scale=0,acodec=mp4a,ab=128,channels=2,samplerate=44100} :sout-rtp-sap :sout-rtp-name= :sout-standard-sap :sout-standard-name= :sout-standard-group= :sout-all :ttl=1 :sout-keep

Then export to a file, and try to import it back. There is a syntax error.
