  [DELTA]

    * Release 3.23

    Yes, this is a packaging error. Mea culpa. In the future
    test releases will be 3.23_01, etc.

    See https://twitter.com/frioux/status/429245594180128769
    for context.

3.22_02 - Wed Feb  5 05:08:34 UTC 2014
    * Add a pager that doesn't redirect stdin RT#85173
      Added a special pager environment variable for use
      when perldoc is in the -m mode that doesn't
      redirect STDIN.  Set PERLDOC_SRC_PAGER to use.

      As in:

      PERLDOC_SRC_PAGER=/usr/bin/vim perldoc -m File::Temp

    * Teach ToTerm.pm to get terminal width RT#85467
      Get a terminal width and pass it to Pod::Text::Termcap
      from one of these sources (in order):
          1. An explicit width set from command line with -w
          2. MANWIDTH environment variable
          3. stty output
          4. The default width of 76 (same as Pod::Text)

3.22_01 - Sat Feb  1 05:00:13 UTC 2014
    * Match =item more carefully when scanning perlfunc.
      Fixes RT #86795. Previously matches could be generated
      on words like 'size' and 'precision' which are not
      Perl functions.
    * Cleanup code related to mandoc RT #85844
      Patch by Ingo Schwarze
    * Re-add '-U' flag to skip attempting to drop
      privileges. RT #87837
    * Do not install to INSTALLDIRS after Perl 5.11 RT #89756
    * Refactor search_perlop (finds operators like 'q'
      'qq' 'tr' and others) RT #86506. Previously most of
      the text generated was incorrect.
    * Fix wrong version in DEBUG output from ToTerm.pm RT #85468
    * Fix POD errors when scanning parts of perlfunc RT #86472
      Patch by Shlomi Fish.
