Update to 1.31
    
    - New upstream release 1.31
      - New co-maintainer (Gabor Szabo)
      - Merge .pod and .pm and move them to lib/
      - Move the test and the code to standard location /t in the distribution
      - Eliminate indirect calls in tests
      - Use Test::More instead of home-brew testing
      - Typos fixed in pod (CPAN RT#86852)
      - Changes file re-ordered and standardized
      - Refactored test script
      - Eliminate indirect calls in the code and in the docs
      - Use Perl::Tidy to unify layout
      - Added use warnings;
      - IO::Tty prerequisite version 1.03 → 1.11
      - More test diagnostics
      - Tests added for CPAN RT#62359
      - Skip the bc test on OS-es where it has been failing
      - Stop inheriting from Exporter
      - Eliminate $` and $' from the code (part of CPAN RT#61395); this fix might
        break some existing code in some extreme cases when the regex being matched
        has a lookbehind or a lookahead at the edges
      - Remove $& and $`, fixing the rest of CPAN RT#61395
      - Various code refactoring declaring loop variables, parameter passing,
        return undef, etc.
      - Croak if undef passed to _trim_length
      - Update documentation according to CPAN RT#60722
      - CPAN RT#47834: after a failed call to ->expect, the ->match and ->after
        will return undef and ->before will return the content of the accumulator;
        earlier they retained the values obtained during the last successful match
        (->before will return undef the first time but later, if we call
        ->clear_accum, it will start returning the empty string)
      - In the tests, add special treatment for $^O=midnightbsd and dragonfly, and
        for $^O=linux as well
      - Test t/11-calc.t also got some special treatment
    - This release by SZABGAB → update source URL
    - As we need Test::More ≳ 0.98, drop support for old distributions
