For example:

  [ one
  , two
  , three
  ]

This does not affect coding styles that don't put commas at the
beginning of lines.

Like this: 'atom$'.  In that example, the last single quote should be
recognised as ending the atom.  This needs a font-lock workaround
similar to the one for strings.

In some situations, the indentation of record fields in Emacs was
strange. This example below shows how Emacs previously would indent
two similar pieces of code very differently:

    some_function_with_a_very_long_name() ->
        #'a-long-record-name-like-it-sometimes-is-with-asn.1-records'{
                                         field1=a,
                                         field2=b}.

    x() ->
        #some_record_name{
       field1=a,
       field2=b}.

This changes the indentation to be like below for both cases:

    some_function() ->
        #some_record{
           field1=a,
           field2=b}.

An example that didn't work previously.
case Foo of 
     {ok, X} ->
         ok;
     _ ->
         catch file:close(FD)
end.

Type highlighting reported by Jay Nelson
  non_neg_integer() will highlight purple but pos_integer() does not.

Closing record indentation problem reported by Maxim Treskin:

-record(state, {
         sequence_number = 1          :: integer()
                                                      }).

Trying to indent this piece of code by hitting TAB on each line:

foo() ->
    [#foo{
	foo = foo}].

used to cause an error.  Fix by ignoring errors when trying to skip
backwards from a record.

Also add this test case to test.erl.orig and test.erl.indented.
