It is hard to make a script based on the current output of quota command, because when the file system has a long name (>15 char), quota display two lines instead of one. I think it was better to show only one line, even if it not whell formated
Output of quota(1) is primarily meant to be directly seen by a user. But I'll add an option to quota(1) command for not truncating the device name as I agree that sometimes using it in scripts can make sense.
I added the option (-w) to quota(1).
