I still say it's not a very good idea to do this

In order to make an informed decision, what are you refering to Wolfgang ?

Your \EveryPar hackery.

What is it about it that it's a bad idea ?

Who knows, it could work or fail in a few cases.

I apologize for my ignorance, I'm still confused with this one (see attachments)...

Why?

(step 3: ...) is typeset one first paragraph too far.

\def\doCountLines#1\par{%
      \begingroup
      \setbox\scratchbox\vbox{#1\par}%
      \getnoflines{\htdp\scratchbox}%

      \global\parlines=\noflines\relax
%       (step 2: P\space\the\parnumber, \the\parlines\space L)

      \ifnum \parlines = 1
              (step 3: P\space \the\parnumber, \the\parlines\space L)%
      \fi

      \endgroup#1\par}
