Currently I'm reading NEWS.28 and noticed this section marked by
+++ as documented in the manual:

  +++
  ** New user option 'next-error-message-highlight'.
  In addition to a fringe arrow, 'next-error' error may now optionally
  highlight the current error message in the 'next-error' buffer.
  This user option can be also customized to keep highlighting on all
  visited errors, so you can have an overview what errors were already visited.

But the source of the manual has only these two lines:

  @findex next-error-message
  @vindex next-error-message-highlight

'next-error-message' is a face and can be removed from the index.
But 'next-error-message-highlight' is a user option, and when
the reader selects it from the Info index, its page says nothing
about this option.  This patch fills the gap:
