Glancing over `info coreutils "fmt invocation"', I would say yes,
mostly.  --crown-margin would be challenging, but I think doable.  I'm
not sure what --tagged-paragraph is getting at, but if I understand the
documentation correctly, then its implementation should be similar to
--crown-margin.  Finally, I would probably leave out "[trying] to avoid
line breaks after the first word of a sentence or before the last word
of a sentence".

Otherwise, it looks like a workable idea.  Where would this library of
shell script functions reside?
