Fix indentation of records with line breaks inside lists

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.
