[pmwiki-users] brackets without space

[JB]

I need regular expression help.

Here is my current regular expression:

  /^\\[([^[].*?)\\]/

This will find 

    [anytext]
    [abcdefghij]
    [ ]

and not 

    [[alink]]


But it will not find "[]" - two
brackets without a space between them.

Can I make it work the same way except also 
allow "[]"?



Thanks
