Jürgen Spitzmüller 2c796e8fcb * csv2lyx:
- make output more closely to format 276. This also prevents lyx2lyx from choking
	  while importing a csv file into 1.6.

Remarks:
If your .csv file contains special characters (e. g. umlauts,
accented letters, etc.) make sure it is coded in UTF-8 (unicode).
Else LyX will loose some cell contents.'''
