.UL sort
sorts its input into ascending lexicographic order.
Two lines are in order if they are identical or if the leftmost character
position in which they differ contains characters which are in order,
using the internal numeric representation of the characters.
If a line is a proper prefix of another line, it precedes that line in
sort order.
