camel_mime_parser_tell() returns an offset from where it started parsing,
* 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. svn path=/trunk/; revision=2680
