svn commit: r356209 - head/share/man/man7

[John Baldwin]

Author: jhb
Date: Mon Dec 30 22:05:57 2019
New Revision: 356209
URL: https://svnweb.freebsd.org/changeset/base/356209

Log:
  Formatting fixes for tables, no content changes.
  
  - Add missing .Pp after the end of some lists so that there is a blank
    line before the subsequent paragraph.
  - Use a more typical '-tag' bullet list of the make variable descriptions
    at the end.  This adds separation between bullets and is the formatting
    typically used in manpages for this sort of list.
