Yes i have looked at it - the problem is the patch assumes that each 
tiff/g3 page has the RTC characters appended to it which is not necessarily 
true.  Each page should be checked, by looking  at the last few characters 
to see whether the RTC chars are present.

PS I am glad someone else is looking at this i have had this problem on my 
todo list since the end of 
1998(http://www.hylafax.org/archive/1998-12/msg00015.php) but have not had 
any time to do anything about it :-(
