bad data. 2. Fix a bug that could allow a Koetter-Vardy false decode instead of a valid Berlekamp-Massey decode, sometimes leading to program crash. 3. Many more edits in the User's Guide, *.adoc files. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@3664 ab8295b8-cf94-4d9e-aec4-7959e3be5d79
