Good day Lars -

   Thanks,  I will test with the man.el from Emacs 28 .

   But if it still does fontification on the fly, for each
   buffer read, I suspect it will still have the problem -
   there is no guarantee that the buffer did not end
   with only a partial escape sequence, which is
   then ignored.

   Unless this situation is detected and handled
   (check for partial escape at end, remove it,
    prefix it to the next buffer read)
   then it will still occur.
   I thought it much more complicated to try
   to do that than to just wait until the complete
   man process output has been read, then
   fontify the buffer - much simpler, it always
   works, only a brief display of unfontified contents
   for long man-pages occurs.

  I'll grab just the man.el from Emacs 28 and give it
  a try - I don't want to mess around with RPM
  packaging & building now to build the whole
  thing, I'll wait for the Fedora package to come out.

Thanks & Best Regards,
