BUG:	Wfits sometimes crashed with a segmentation violation when
	files were written with a non-standard block size (block_factor > 10).
	The error was in the code which 0-filled the unused portion of the
	last output block,  and occurred if the unused portion of that
	block was greater than 2880 bytes.

	Rfits sometimes reported read errors when it tried to read tapes
	with a non-standard block size (blocks not a multiple of 2880
	bytes). Rfits was not always counting the number of characters read
	from the tape correctly when the read attempted to cross tape record
	boundaries. Tapes with small block sizes like 512 and 1024 were
	the most affected.

STATUS:	Both bugs have been fixed in version 2.10 and the 2.9.1 patch.
