[PATCH 2/6] Make xdl_hash_record_with_whitespace ignore eof

[Thell Fowler <git@tbfowler.name>]

  - When xdl_hash_record_with_whitespace encountered an incomplete
    line the hash would be different than the identical line with
    either --ignore-space-change or --ignore-space-at-eol on an
    incomplete line because they only terminated with a check for
    a new-line.
