title: Can VIM uncompress gzip files automatically with a different file extension?
body: <p>Vim automatically expands <code>.gz</code> files when I open them up, which is great.  However, it doesn't reccognize <code>.GZ</code> (upper case) in the same way.  Unfortunately I cannot change the file extensions of the files I'm working with for various reasons.  Is there a realatively simple way to register with VIM that <code>.GZ</code> are the same as <code>.gz</code> files?</p>
