'-y' - STORE FILES WITH RATIO > X%

This option causes LZX to store files which have a compression ratio of
greater than the specified percentage.  For example '-y95' would cause LZX to
store all files which compressed to 95% or more of their original size.

Specifying a number greater than or equal to 100 makes no sense; LZX will
always store any file which compressed to more than its original size.

This option is a carry-over from the other Amiga archivers which often
decompress poorly compressed files very slowly.  LZX is very fast at
decompressing any type of file, but it must be said that decompressing
a stored file is quicker (it's all disk i/o and very little CPU usage;
for a stored file, the disk i/o will be the bottleneck).

Note that merged file groups are treated as one file for all intents and
purposes; therefore, the whole merged group will be stored if the
compressed group is greater than the group's combined original size.
