This release fixes a few minor issues.

## 2019 12 03

    - Fixed issue RT#131115: -bli option not working correctly.
      Closing braces were not indented in some cases due to a glitch
      introduced in version 20181120.

    - Fixed issue RT#130394: Allow short nested blocks.  Given the following

        $factorial = sub { reduce { $a * $b } 1 .. 11 };
   
      Previous versions would always break the sub block because it
      contains another block (the reduce block).  The fix keeps
      short one-line blocks such as this intact.

    - Implement issue RT#130640: Allow different subroutine keywords.
      Added a flag --sub-alias-list=s or -sal=s, where s is a string with
      one or more aliases for 'sub', separated by spaces or commas.
      For example,

        perltidy -sal='method fun' 

      will cause the perltidy to treat the words 'method' and 'fun' to be
      treated the same as if they were 'sub'.

    - Added flag --space-prototype-paren=i, or -spp=i, to control spacing 
      before the opening paren of a prototype, where i=0, 1, or 2:
      i=0 no space
      i=1 follow input [current and default]
      i=2 always space

      Previously, perltidy always followed the input.
      For example, given the following input 

         sub usage();

      The result will be:
        sub usage();    # i=0 [no space]
        sub usage();    # i=1 [default; follows input]
        sub usage ();   # i=2 [space]

    - Fixed issue git#16, minor vertical alignment issue.

    - Fixed issue git#10, minor conflict of -wn and -ce

    - Improved some vertical alignments involving two lines.
