+ - Optimized the handling of larger block sizes (rsync used to slow to
+ a crawl if the block size got too large). Also cap the block size.
+
+ - Optimized away a loop in hash_search().
+
+ - Make sure that a filename that contains a newline gets mentioned with
+ each newline transformed into a question mark (which makes parsing
+ the verbose output via script more dependable).
+
+ BUILD CHANGES:
+
+ - Added a "gen" target to rebuild most of the generated files,
+ including configure, config.h.in, the man pages, and proto.h.
+
+ - If "make proto" doesn't find some changes in the prototypes, the
+ proto.h file is left untouched (its time-stamp used to always be
+ updated).
