s/most/some/;

For example, the code has fun heuristics to understand that things
like "-- >8 ---- >8 -- cut here -- >8 ---- >8 --" is a scissors
line, but we do not document it.

But what we agreed is that it is a bad idea to even attempt to
describe the heuristics down to the details and sell the feature as
"we accept anything that resembles a perforation drawn or printed on
paper".  Instead we are giving less choices to make it easier for
users to follow, and the updated text is a move in that direction.

So selling this change based on "the existing description does not
give enough" is not good.

    The text tries to say the code accepts many variations that
    looks remotely like scissors and perforation line, but gives too
    little detail for users to decide what is and what is not taken
    as a scissors line for themselves.  Instead of describing the
    heuristics more, just spell out what will always be accepted,
    namely "-- >8 --", as it would not help users to give them more
    choices and flexibility and be "creative" in their scissors
    line.

perhaps?

We want to say "e.g.", i.e. 'a scissors line (e.g. "-- >8 --")', in
order to hint that we may accept other forms [*1*], and also to hint
that we do not want to go int details.

Other than that, I like the conciseness of the updated text.


[Footnote]
*1* This is primarily to be friendly to left-handers to let them
write "-- 8< --".
