Ruslan Ermilov 80e770cf63 - Add an OPTIONAL_MANPATH directive (same as MANDATORY_MANPATH,
except an absence of the directory is not considered an error
  and doesn't produce a warning).
  Put /usr/local/lib/perl5/*/man under OPTIONAL_MANPATH.

- An order of directives in manpath.config is now irrelevant.

- Get rid of infinite loop when PATH is unset or NULL, and
  MANDATORY_MANPATH directory doesn't exist.

- mdoc(9)ify manpage.
