Dear Maintainer,

two dots in a filename cause miniunzip to remove everything in the path up to those two dots:

   $ mkdir testzip
   $ touch testzip/abc..def testzip/123..def
   $ zip -r testzip testzip
   $ rm -rf testzip
   $ miniunzip testzip
   MiniUnz 1.01b, demo of zLib + Unz package written by Gilles Vollant
   more info at http://www.winimage.com/zLibDll/unzip.html

   testzip.zip opened
   creating directory: testzip/
   extracting: def
   The file def exists. Overwrite ? [y]es, [n]o, [A]ll:

Instead of creating those two files in the testzip subdirectory, miniunzip
tries to create two files both called "def" in the current directory.
