Bug#772080: mc: Hanging when trying to unzip an password saved file

[Dmitry Borisyuk]

Control: tags -1 patch 

Hi,

this is very easily understood.
When the file is encrypted, the unzip process asks for password interactively,
but the user neither sees the prompt nor can enter the password, thus mc hangs.

A very simple workaround is to supply empty password with -P. Here is the patch:

You may patch /usr/lib/mc/extfs.d/uzip directly, no need to recompile mc.
If you wish to patch the source, then apply the patch to 
src/vfs/extfs/helpers/uzip.in
