Why -y?  And why a short name at all?  I don't expect this to be 
something that people will want to type by hand.

Come to think of it, gzip should also do an fsync, or at least an 
fdatasync, on the destination's directory before removing the source. 
And this suggests that any long option name shouldn't be something 
syscall-specific like '--no-fsync', but should instead be something more 
general and easy to remember, e.g., '--hasty'.
