This gives better compression for large values of '--match-length' without being slower. * encoder.h, encoder.c: Optimize pair price calculations, reducing compression time for large values of '--match-length' by up to 6%. * main.c (decompress): Print only one status line for each multimember file when only one '-v' is specified. 2011-01-11 Antonio Diaz Diaz <ant_diaz@teleline.es> * Version 1.1 released. * Code has been converted to 'C89 + long long' from C99. * decoder.c: '-tvvvv' now shows compression ratio. * main.c: Match length limit set by options -1 to -8 has been reduced to extend range of use towards gzip.
