Are we already sometimes adding a scissors line in that file?  The
impression I was getting was that the change in the step 2/2 is the
only reason why this becomes necessary.  In which case this change
makes no sense as a standalone patch and requires 2/2 to be a
sensible change, no?

This one is done before we show a block of text, which looks correct.

The correctness of this one in an if/elseif/else cascade is less
clear.  When "contains scissors" logic does not kick in, we just
have a scissors line here (i.e. the original behaviour).  Now when
the new logic kicks in, we not just omit the (extra) scissors line,
but also say "Please enter the commit message..." which is the
message used with the "comment line char" mode of the clean-up.

I wonder if this is what you really meant to have instead:

>  		else if (cleanup_mode == COMMIT_MSG_CLEANUP_SCISSORS &&

That is, the only behaviour change in "merge contains scissors"
mode is to omit the cut line and nothing else.
