Yes, `insert-file-contents' (which is the primitive used by
`revert-buffer') does indeed some clever things to ensure that only the
parts of the buffer that are different from the corresponding file are
replaced.  That keeps markers in the unchanged parts intact.

However, with compressed files the file contents and the buffer contents
are completely different, thus everything's replaced.
