Upstream changes:
2016 03 02
      - RT #112534. Corrected a minor problem in which an unwanted newline
        was placed before the closing brace of an anonymous sub with
        a signature, if it was in a list.  Thanks to Dmytro Zagashev.

      - Corrected a minor problem in which occasional extra indentation was
        given to the closing brace of an anonymous sub in a list when the -lp
        parameter was set.

  2016 03 01
      - RT #104427. Added support for signatures.

      - RT #111512.  Changed global warning flag $^W = 1 to use warnings;
        Thanks to Dmytro Zagashev.

      - RT #110297, added support for new regexp modifier /n
        Thanks to Dmytro Zagashev.

      - RT #111519.  The -io (--indent-only) and -dac (--delete-all-comments)
        can now both be used in one pass. Thanks to Dmitry Veltishev.

      - Patch to avoid error message with 'catch' used by TryCatch, as in
           catch($err){
              # do something
           }
        Thanks to Nick Tonkin.

      - RT #32905, UTF-8 coding is now more robust. Thanks to qsimpleq
        and Dmytro for patches.

      - RT #106885. Added string bitwise operators ^. &. |. ~. ^.= &.= |.=

      - Fixed RT #107832 and #106492, lack of vertical alignment of two lines
        when -boc flag (break at old commas) is set.  This bug was
        inadvertantly introduced in previous bug fix RT #98902.

      - Some common extensions to Perl syntax are handled better.
        In particular, the following snippet is now foratted cleanly:

          method deposit( Num $amount) {
              $self->balance( $self->balance + $amount );
          }

        A new flag -xs (--extended-syntax) was added to enable this, and the default
        is to use -xs.

        In previous versions, and now only when -nxs is set, this snippet of code
        generates the following error message:

        "syntax error at ') {', didn't see one of: case elsif for foreach \ 
given if switch unless until when while"
