Thanks for doing that!
I'm not sure that it belongs in sort though as it's quite specialized.
Also there is ambiguity in the length of a line.
I.E. is it bytes, characters or screen cells.
Also it's quite easy to achieve with existing tools:
awk '{print length, $0}' <file | sort -n | cut -f2- -d' '
What might be better would be to add an option
to `wc` to get it to prepend various counts to a line
(words, chars, bytes, cells), which then could be
sorted and stripped as above.
cheers,
Pádraig.
