Log message:
Bump for perl-5.20.0.
Do it for all packages that
* mention perl, or
* have a directory name starting with p5-*, 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:
Import Log-Report-Optional-1.00 as devel/p5-Log-Report-Optional.

This module will allow libraries (helper modules) to have a dependency
to a small module instead of the full Log-Report distribution. The full
power of Log::Report is only released when the main program uses that
module. In that case, the module using the 'Optional' will also use the
full Log::Report, otherwise the dressed-down Log::Report::Minimal version.
