OK, good.  But what do you mean by "style"?
Do you mean that you want to apply a face to some
parts of some messages?

If so:

1. Do you want to apply the face to the buffer
   _positions_ of those msg parts, as an _overlay_
   property, or do you want to apply it to the
   _characters_ of those msg parts, as a _text_
   property?

2. Are those message parts recognizable/definable
   in a regular way, i.e., as something that you
   can define using one or more regexps?  And do
   you want the face highlighting to be
   automatically reapplied to those parts when
   the same text is visited anew (in the same
   mode), e.g. in a new Emacs session or after
   reverting the buffer?

   If the answer is yes then look at using
   `font-lock-mode' to define and highlight those
   parts.  If the answer is no then maybe look
   at using ad hoc highlighting, such as you get
   with library `highlight.el':

Knowing the answers to these, and perhaps other,
questions might help you direct your search for
tutorials (e.g. whether to look for tutorials
that involve font-lock highlighting).

The more you can specify about what you're
interested in, the more helpful people and search
can be.
