proposal: psql - breaking rows in white chars for wrapped format

Hello

Current wrapped format doesn't break rows well (after white chars). I
propose change this behave (to more typical for text):

Current:

postgres=# \pset format wrappedOutput format is wrapped.
postgres=# select a from test;                          a
--------------------------------------------------------There are many variations of passages of Lorem Ipsum available,
butthe majority have suffered alteration in some form, by injected humour, or randomised words which don't look even
slightlybelievable. If you are going to use a passage of Lorem Ipsum, you need to be sure there isn't anything
embarrassinghidden in the middle of text. All the Lorem Ipsum generators on the Internet tend to repeat predefined
chunksas necessary, making this the first true generator on the Internet. It uses a dictionary of over 200 Latin words,
combinedwitha handful of model sentence structures, to generate Lorem Ipsum which looks reasonable. The generated Lorem
Ipsumis therefore always free from repetition, injected humour, or non-characteristic words etc.

It should be implemented via checking white chars inside
strlen_max_width function.

any notices, ideas welcome
