[Alexander Grischuk]: When mount zip file with filenames stored like ./dir/file (instead dir/file), 
glob shows nothing. Looks like it's bug in depth calculation logic. 
I have used ActiveTcl8.4.13 stable.
To fix this problem I just patch code to eliminate "." path elements. Here is diff:

388,397c388
< 
<     set path [read $fd [u_short $flen]]
<     set sb(name) ""
< 
<     foreach el [file split $path] {
<         if {$el ne "."} {
<     		set sb(name) [file join $sb(name) $el]
<     	}
<     }
<     
---
>     set sb(name) [read $fd [u_short $flen]]
464,471c455
<     set name ""
< 
<     foreach el [file split [string tolower $path]] {
<         if {$el ne "."} {
<     		set name [file join $name $el]
<     	}
<     }
< 
---
>     set name [string tolower $path]

I didn't test enough, but such patch solves my problems.
