I gave an example of such code in the post which opened this thread.  To
recap:

(newline)
(insert "(vi)")
(fill-paragraph)

The `-and-indent' behaviour messes up the indentation of "(vi)" and
causes it to get re-attached to the previous paragraph.

See above.  Any code which is interested in filling (or, possibly, even
margins, if anything actually uses these) will get broken by the
`-and-indent'.
