Translating entities by name ultimately relies on
Commonmark.Entity.lookupEntity, which de facto requires the entity name
to be followed by a semicolon. Paste a semicolon onto the end of the
entity name read from POD to look it up.
Fixes#11015
Pod ("Plain old documentation") is a markup languaged used principally
to document Perl modules and programs. Since it was originally meant to
be translated pretty directly to man, the semantics are fairly simple.
This Pod reader was developed with reference to the canonical user and
implementer documentation of Pod: https://perldoc.perl.org/perlpod and
https://perldoc.perl.org/perlpodspec.
There are 1490 .pod, .pl, and .pm in the Perl 5.34 distribution found in
/System/Library/Perl on my mac. Of those, this reader dies with a parse
error on 7 of them. All of them seem to be cases where pod commands are
found within a non-colon-prefixed =begin/=end. perlpodspec says I may
treat this as an error.
[API change] adds readPod
