Do it for all packages that
* mention perl, or

* depend on a package starting with p5-
like last time, for 5.18, where this didn't lead to complaints.
Let me know if you have any this time.

Log message:
Bump all packages for perl-5.18, that
a) refer 'perl' in their Makefile, or
b) have a directory name of p5-*, or

Like last time, where this caused no complaints.

Log message:

I hope that's all of them.
