bug#23677: sort --debug not ignoring punctuation when sort does

[Karl Berry]

    They are not ignored, just considered only secondary, if the first
    order characters didn't provide an ordering.

Ok.  One would have no clue of that, either, from the --debug output.

sort obviously knows the exact rules defined by the locale, or it
couldn't do its job.  How about a way to dump the rules in some
human-readable way?  (In sort or another utility or a separate program
or whatever.)  Similar to how James Youngman found a way to write out
regex definitions in Texinfo ... just a wish ... -karl
