Hello:

I'm decompressing some very important files as we speak, and while attempting to do so, it returned a warning that "entries after the first were ignored" and failed to output any useful files. The sample usage was:

gzip -d foo.zip

This returned only a single, small, corrupted file called "foo." Now, I only see one entry there, and Googling the problem really didn't help. More to the point, though...the first time I did this foo.zip was deleted. Which is a problem since, as I mentioned, these are important files. Upon further examination, I see that the -k is necessary to prevent this from happening, but I'm surprised that a) default behaviour is to delete files after usage, and b) it would do so even after a warning or error? This latter behaviour is what I perceive to be a bug, above all else, though I find the default behaviour in general to be baffling and unintuitive.

Thanks in advance.
