Changed the parsing of suffixes for --min-size and --max-size a little.

-The suffixes are as follows: "K" (or "k") is a kilobyte (1024),
-"M" (or "m") is a megabyte (1024*1024), and "G" (or "g") is a
-gigabyte (1024*1024*1024).
-If you want the multiplier to be 1000 instead of 1024, suffix the K, G, or
-M with a "T" (or "t") to indicate that a power of 10 is desired.
+The suffixes are as follows: "K" (or "KiB") is a kibibyte (1024),

 Finally, if the suffix ends in either "+1" or "-1", the value will
 be offset by one byte in the indicated direction.
