+2007-10-08  Ben Pfaff  <blp@gnu.org>
+
+	Fix bug #21280.  Thanks to John Darrington for review.
+
+	* file-name.c (create_stream): New function.
+
+	* por-file-writer.c (pfm_open_writer): Use fh_open to open the
+	file handle before creating the file, to ensure that we don't
+	truncate a file that we're reading.  Make code easier to read by
+	using create_stream.
+
+	* sys-file-write.c (sfm_open_writer): Ditto.
+
+2007-10-01  Ben Pfaff  <blp@gnu.org>
+
+	Fix bug #21192.  Thanks to John Darrington for review.
+
+	* casereader.c (casereader_read): Decrement case_cnt before
+	calling the casereader's "read" member function, so that we
+	interact properly with lazy_casereader.
+
+	* datasheet.c: Add regression test for above bug fix.
+	(clone_datasheet): New function.
+	(lazy_callback): New function.
+	(check_datasheet_casereader): New function.
+	(check_datasheet): Check datasheet contents are reported correctly
+	through an ordinary casereader and a lazy casereader.
+	(clone_model): Use clone_datasheet.

+
+	Patch #6210.  Reviewed by John Darrington.
+	* settings.c: Drop "long view", which is not needed any longer.
+	(static var long_view): Removed.
+	(force_long_view): Removed.
+	(get_viewwidth): Removed.
+	(init_viewport): Removed long_view reference.

+	
+	* settings.c settings.h: Changed viewport's length and width to be 
+	owned by the user interface which uses the data library.  This allows
+	better abstraction, and makes dynamically adjustable dimensions easier.
