The skip() implementation for the compressed file input stream incorrectly
handled the case of skipping to the end of file: In that case we just need
to update the file pointer, but not skip anywhere in the compressed disk
file; In particular, we must NOT call locate() to find the relevant on-disk
compressed chunk, because there is none - locate() can only be called on
actual positions of bytes, not on the one-past-end-of-file position.
