perl5.git is now in sync with metaconfig.git commit
7c34fa4e8142642c6e2978f0307e925898465f58

Work done at the QAH in Rugby.
Multi-thanks to Aaron for helping out here. You're doing a great job!

This avoids the following error, reported by Jitka Plesníková
<jplesnik@redhat.com> in a test of RC1:

op.c: In function 'Perl_ck_ftst':
op.c:9754:58: error: format not a string literal and no format arguments [-Werror=format-security]
                 Perl_warner(aTHX_ packWARN(WARN_SYNTAX), array_passed_to_stat);

In addition, the string in question is now made const.

Give people a heads up that in the next major perl release, subroutine
signatures may no longer populate @_ by default.

See http://nntp.perl.org/group/perl.perl5.porters/235332.

Only the text of these should be present in a delta, with a link to the
full explanation.  Most of perldelta conformed to this, but not all.

I also removed one instance of a 5.23-only bug, which isn't relevant to
a dot zero delta

 * behaviour -> behavior
 * =over -> =over 4
 * Add =items for consistency
 * Capitalization fixes

Some of this was suggested by Jarkko Hietaniemi

This fixes the 5.24 part of [perl #127899].

(Thanks, Ed Avis!)

We say something here that is no longer true; update it.

This includes deleting some bug fixes for things introduced in the 5.23
series, and so not relevant to a dot zero perldelta

This commit is just prep, turning blead into the branch from which
v5.24.0 will be released, after suitable testing.
