Bug#995244: rxvt-unicode: confirm-paste considers [] as control chars

[Jakub Wilk]

Package: rxvt-unicode
Version: 9.26-2
Tags: patch

The confirm-paste extension gives me spurious warning when I try to 
paste square brackets:

  Pasting 2 control characters, continue? (y/n)
  []

The attached patch fixes this.
