[texhax] Under-Sized Angle Brackets

[hh]

Hello, 

in correction to my mail before: It would be enough if you replace in the 
sample below the \lange+\rangle by e.g. \Vert. Works out fine.

Anf if you look up the symbols-A4.pdf (see CTAN) there are some more 
possibilities for large brackets (Table 142ff).
