Re: [PATCH 00/13] Update versions of libcurl and Perl

The final commit introduces a small but useful change that we can now
take advantage of with our newly updated Perl dependency as an example

Quite honestly, these two changes, each of which is a one-liner, are
so boringly trivial for being "too noisy".  But on the other hand, I
am not sure it demonstrates why it is a "generally beneficial
change" sufficiently well, either.  The pre-s///r idiom

    (my $result = $orig_to_be_kept) =~ s/...//;

was concice enough that

    my $result = ($orig_to_be_kept =~ s/...//r);

does not make all that much improvement.  Where it shines, I would
imagine, is to rewrite an original that did not use the idiom using
the 'r' modifier, but fortunately we didn't have such a code?
