Re: How to wrap lines?

I'm trying to understand the variable bbdb-wrap-column.

First of all, there seems to be some property called INDENT which
interferes with the behaviour of this variable: I read in bbdb.el

--8<---------------cut here---------------start------------->8---
If INDENT and `bbdb-wrap-column' are integers, insert line breaks in
between elements of LIST if otherwise inserted text exceeds
`bbdb-wrap-column'."
  ;; `truncate-lines' is fine for one-line layout.  But it is annyoing
  ;; for records that are displayed with multi-line layout.  Non-nil
  ;; `word-wrap' would be much nicer.  How can we switch between non-nil
  ;; `truncate-lines' and non-nil `word-wrap' on a per-record basis?
  ;; The following code is an alternative solution using
  ;; `bbdb-wrap-column'.
--8<---------------cut here---------------end--------------->8---

Does anybody understand what is INDENT?

Does anybody understand how bbdb overwrites the emacs default which is
to wrap lines?

Can anybody rewrite the second sentence in the commented portion above,
in a way that makes sense in the English language? (I don't understand
what it means for a record to be displayed with multi-line layout)?
