For filenames like /vsizip//path/to.zip/path/inside/it.tif

The good news is that in trunk I've recently relaxed that since I needed to 
deal with .tar files with extensions not ending with .tar, so you can now use 
syntaxes like

/vsizip/{/path/to/the/zip.any_or_no_ext}
/vsizip/{/path/to/the/zip.any_or_no_ext}/path/inside/it

And you can even nest it as many times as you need in case of zip inside zip 
etc...

/vsizip/{/vsizip/{/path/to/the/zip.any_or_no_ext}/path/inside/it}/....
