The survey() method in Pod::Simple::Search now ignores duplicate
files with varying lettercasing on case-insensitive file systems.
This allowsWhen pondering files in a given directory, the survey() method in
Pod::Simple::Search now prefers files with extensions in the
following order: no extension, .pod, .pm, .plx, .pl.The find() method in Pod::Simple::Search now records the './pod'
subdirectory of each directory it considers in such a way as to
preserve its case on the file system.The find() method in Pod::Simple::Search now tries harder to find
the proper file on case-insensitive file systems when searching
for modules starting with "Pod". For example, when searching for
'Pod::Perldoc' it now returns a file ending in 'Pod/Perldoc.pm'
instead of 'Pod/perldoc.pod', as the latter is actually the
documention for the 'perldoc' program.
