svn commit: r360458 - head/share/man/man4

[Benedict Reuschling]

Author: bcr (doc committer)
Date: Wed Apr 29 11:25:04 2020
New Revision: 360458
URL: https://svnweb.freebsd.org/changeset/base/360458

Log:
  When copying and pasting the code in the EXAMPLE
  section, it would result in the following error:
  
  "ngctl: send msg: Invalid argument"
  
  The reason for this is the missing whitespace to
  separate the arguments. When adding the whitespace,
  the example works as intended.
