[encodings 0/4] Improve support for input encodings

[Ben Pfaff]

This has been cooking for some time but I was spurred to finish it
up by this recent Debian bug report:
        http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=676371

Ben Pfaff (4):
  PRINT SPACE: Fix missing fh_unref() on error path.
  line-reader: New library for reading a file line-by-line.
  Add ENCODING subcommand to several commands.
  text-data-import-dialog: Allow user to choose input encoding.
