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.

BUG:	IRAF 2.9 rfits was not reading fits files with short last logical
	records correctly, i.e. records not correctly padded out to 2880
	bytes. For each output image line contained or partially contained
	in the final short record, an error message was generated,
	and incorrect data was written to the output image.

STATUS:	The bug has been fixed in 2.10 and was not a problem in IRAF 2.8
	and earlier. The workaround is to use Unix dd command or the IRAF
	reblock task to reformat the file.

BUG:	The colon commands :rinner and :router were incorrectly defined as
	:rin and :rout in the pexamine definitions file. In addition the
	new router value was being written back into the rinner parameter,
	a bug that was masked by the previous problem.

STATUS:	Fixed for the next release of iraf. The workaround is to use the
	:epar radplot command and edit the parameter set as a whole.
