Wrong assumption.

RTFM shows:

`$(sort LIST)'
     Sorts the words of LIST in lexical order, removing duplicate
     words.  The output is a list of words separated by single spaces.
     Thus,

          $(sort foo bar lose)

     returns the value `bar foo lose'.

     Incidentally, since `sort' removes duplicate words, you can use it
     for this purpose even if you don't care about the sort order.



Best regards,

Wolfgang Denk
