fold(1) and "blank" and add lazy option
-s Fold line after the last blank character within the first width
column positions (or bytes).
I plan to add to that -s description: "If a blank character does not
exist within the width, then a longer line will still be split at
It specifically says "blank". But code has:
if (buf[i] == ' ')
last_space = i;
It doesn't use isblank. I may change the manual page to say "space"
instead (since \t has a different purpose in fold). Anyways "-s" for
*s*pace makes sense.
The -[0-9] arguments aren't documented in manual page nor in usage. Why?
Historical, but planned to be removed to just use -w instead?
I was thinking of adding a lazy option so when using -s it won't still
split at width if there is no space up to the width. So some
output lines may be longer than width when using the option.

p.s. I am looking for a LaTeX formatter, that can fold and possibly
justify lines. It must know LaTeX, for example, if it folds a % comment,
then it should add a % to continue the comment.
