replace some hardcoded "sub" instances with cperl-sub-regexp
realign pattern match grouping comment due to insertion of cperl-sub-regexp
Patch indentation of continued statements inside a block.

For example, with this in .emacs

(setq cperl-indent-level 4                ; 4 character indents
      cperl-indent-parens-as-block t      ; indent parens like blocks
      cperl-continued-statement-offset 2
      cperl-continued-brace-offset 0
      cperl-close-paren-offset -4
      cperl-tabs-always-indent nil
)

Without the patch it indents like this.

role {
    has foo =>
      is      => 'rw',
        isa     => 'Int',
          default => 0;
}

With the patch it indents correctly.

role {
    has foo =>
      is      => 'rw',
      isa     => 'Int',
      default => 0;
}

Note the presense of a block around the statement is necessary.  Without the block
the bug does not appear.
