support for unicode identifiers...

support for unicode identifiers This rewrites some of the regular expressions that are used to match Python identifiers, so that they are unicode compatible. In Python 3, identifiers can contain unicode characters as long as the first character is not numeric. Examples for the changes: • inputtransformer: ``` In [1]: π = 3.14 In [2]: π.is_integer? Object `is_integer` not found. ``` ---------- • namespace: ``` π.is_integ*? ``` or ``` In [1]: %psearch π.is_integ Python identifiers can only contain ascii characters. ``` ---------- • prefilter: ``` %autocall 1 φ = float get_ipython().prefilter("φ 3") # should be 'φ(3)', but returns 'φ 3' ``` ---------- • completerlib: If there is a file e.g. named `π.py` in the current directory, then ``` import IPython IPython.core.completerlib.module_list('.') # should contain module 'π' ```
