Ok.k., zip may have changed its behavior since 1988 - but at least 
some unix ports owns that behavior even today. I'm using OS/2 since 
1988 and been fallen in that trap in that early days too often with 
some programs, so I have trainend myself to use filemasks exactly as 
sayed:
- '*'       means all and anything (except file attributes hinders)
             this is the most common form to specify that.
- '*.*'     only files containing at least one '.' in its name.
             you finds different behavior on files with names like
             'letter 24.07.2005'
             This is DOS only style and really outdated. Even newer
             command.com (DOS 5.0 and newer) handles '*' right.

FAT is the only file system that stores NO '.' on disk.
HPFS, HPFS386, JFS uses the char '.' like any other character.
So even zip will give you different file list on the same files when 
they are stored either on FAT or other filesystems when you use a mask 
  like '*.*' or '*'.

On other hand it is more easy to type simply '*' instead '*.*' to get 
anything. The old DOS *.* is outdated since more than 10 years now.

Use google to find comments about "regexp". A mask like '*' is the 
most simple form of that. Most halfways moder programs are able to 
interpret really more complex regexp masks as that (including 
zip/unzip or OS/2 cmd.exe......)
