* camel-mime-part-utils.c
	(simple_data_wrapper_construct_from_parser):
	camel_mime_parser_tell() returns an offset from where it started
	parsing, not necessarily from the start of data. Since we're
	parsing a bounded seekable_stream, we need to add the stream's
	starting bound to camel_mime_parser_tell's return value to
	create the substream in the right place.

	* camel-seekable-substream.c
	(camel_seekable_substream_new_with_seekable_stream_and_bounds):
	say CAMEL_STREAM_UNBOUND rather than -1 in doc.

	* camel-seekable-stream.c (camel_seekable_stream_seek): Add more
	info to docs.
