Disc no./Total discs metadata not written for FLAC files about xld HOT 3 OPEN

XLD writes these tags. See DISCNUMBER, DISCTOTAL, TOTALDISCS field in the file.

When ripping to FLAC+CUE, XLD does not write these tags, and instead just puts:
REM DISCNUMBER
REM TOTALDISCS
in the cue sheet.
It seems to me that these should go in the VORBIS_COMMENT block directly like 
ALBUM, DATE, etc, not just in the CUESHEET field.
See attached files for a test and its results.

That is a different issue (the reporter is talking about the case when 
extract/transcode to multiple files). Please create a new topic.
