Documented field values are case-sensitive

[Russ Allbery <rra@debian.org>]

By previous request, I added the following to document that field values
are case-sensitive unless otherwise said.  I don't think this is a change,
just clearer wording of what's already the case, so I didn't propose this
for seconds.  If you object, of course, please do say.

          Field names are not case-sensitive, but it is usual to
          capitalize the field names using mixed case as shown below.
