Ascii docs, paragraph breaks in lists

[Hal Murray]

What does the 3rd + do here:
 From docs/includes/nts-commands.adoc

+cert+ _file_::
  Present the certificate (chain) in _file_ as our certificate.
  +
  Note that there is no checking on the certificate.
  In particular, it may have expired or may not cover the host name
  used to get to this server or may not be signed by a CA that
  is in the clients root-server collection.

It looks like it is supposed to start a new paragraph, but it shows up in 
the text, both in the man page and the html page.

Removing it but leaving the blank line does the right thing in html but the following paragraph is indented in the man pages.

Anybody understand this area?
