- Updated the address for the FSF in the opening comment. - Standardized the format of the opening comment, including adding a brief description of what's in the file for those that lacked it. - Added some missing copyright lines. - Some minor whitespace tweaks (in a few of the files).
- for protocol version >= 27, mdfour_tail() is called when the block size (including checksum_seed) is a multiple of 64. Previously it was not called, giving the wrong MD4 checksum. - for protocol version >= 27, a 64 bit bit counter is used in mdfour.c as required by the RFC. Previously only a 32 bit bit counter was used, causing incorrect MD4 file checksums for file sizes >= 512MB - 4. -- Craig Barratt
