failures with versions of HTML::Entities older than 3.46. See RT #60450.
Fix for RT-60249. Thanks to John McNamara for the report.
POD tag found inside a complex POD tag (e.g., "C<<< I<foo> >>>") is again parsed as a tag embedded in a tag instead of text and entities. The previous interpretation of `perldoc perlpod` was mistaken. (RT #55602 from Christopher J. Madsen) (reversed commit e1fe004)
Fixed a regression in Pod::Simple::XHTML where '=begin html' blocks were incorrectly escaped rather than simply passed through unmolested.
This allows it to be used by Pod::Simple::HTMLBatch.
