Attached is a patch on top of yours that addresses all the ## no critic
annotations except RequireFilenameMatchesPackage, which can't be fixed
without more drastic reworking of the plperl build process.

Tested on perl 5.8.1 and 5.24.0 by configuring with --with-perl and
--enable-tap-tests followed by make check-world, and running pgindent
--build.

Subject: [PATCH] Fix most perlcritic exceptions

The RequireFilenameMatchesPackage ones would require reworking the
plperl build process more drastically.
