justify: remove "--" from the quoting regex, to avoid false paragraphs

The use of a double dash (for an option name or as sentence separator)
is too common to allow it to be seen always as a comment introducer.
Users of Lua and Postgres will have to redefine 'quotestr' themselves
if they want to be able to rewrap block comments with ^J.

The other characters that were added in commit c5a72103 (!, %, and ;)
are less problematic because they tend to be glued to the end of words,
so they are unlikely to appear at the start of a line.

This fixes https://savannah.gnu.org/bugs/?56462,
and fixes https://savannah.gnu.org/bugs/?56461.

Bug existed since version 4.0, commit c5a72103.
