Oliver Jowett	26feb1d078	Add some testing code that looks for ambiguous syndromes that ... could confuse the partial correction used in DF11. That code shows that yes, there are ambiguous syndromes in the 2-bit correction case only, so disable corrections of more than 1 bit in DF11.	2015-01-23 21:59:31 +00:00
