Import error QT4 backend with python3.2.3

[huard]

On current master, importing matplotlib using QT4Agg backend yields the following error:

File "/lib/python3.2/site-packages/matplotlib-1.4.x-py3.2-linux-x86_64.egg/matplotlib/backends/backend_qt4.py", line 374
    return u'+'.join(mods + [key])
              ^
SyntaxError: invalid syntax

Thanks for reporting this.

I wonder where that came from....I suspect this is my fault from a merge of 1 .3.x.
