Inconistent line-wrapping for procedural types with directives #256

Description

@zaneduffield

Consider the following series of (global) variable declarations.

var
  FuncCallConv:
      function(A: Integer): Integer; stdcall = nil;

  FuncCallConv2:
      function(A: Integer; B: Integer): Integer; stdcall = nil;

  FuncCallConv3:
      function(A: Integer; B: Integer; CC: Integer): Integer; stdcall = nil;

  FuncMultiDirective:
      function(A: Integer; B: Integer): Integer; cdecl varargs = nil;

While atypical, calling convention routine directives can be specified after an anonymous procedural type.
The formatting for these is a bit wonky (wrap_column=60):

var
  FuncCallConv:
      function(A: Integer): Integer; stdcall = nil;

  FuncCallConv2:
      function(A: Integer; B: Integer): Integer;
      stdcall = nil;

  FuncCallConv3:
      function(
          A: Integer;
          B: Integer;
          CC: Integer
      ): Integer; stdcall = nil;

  FuncMultiDirective:
      function(A: Integer; B: Integer): Integer; cdecl
      varargs = nil;

Compare this against the formatting for the equivalent declarations without the directives:

var
  Func: function(A: Integer; B: Integer): Integer = nil;

  Func2: function(A: Integer; BBBBBB: Integer): Integer =
      nil;

  Func3:
          function(
              A: Integer;
              BBBBBB: Integer;
              C: Integer
          ): Integer =
      nil;

I'm not sure exactly what the best formatting is for these cases, but I don't think this is it.
