[IPython-dev] iplib fix (#1)

Fernando (/Alex),

Attached is a patch to the most recent version of iplib which fixes  
the problem reported.  Let's call it fix #1 because it doesn't  
represent the full overhaul of prefilter which is oh-so-close ;-).

Also attached is a patch to test_prefilter.py so that it captures  
this problem (thanks to Alex's detailed report).

The change is just in the first part of the line_split regex, from:

     self.line_split = re.compile(r'^([\s*,;/])'

To:

     self.line_split = re.compile(r'^(\s*[,;/]?\s*)'

The \s* doesn't work inside the [] (special chars are turned off, so  
that matches a '*' or a single whitespace), so the match was failing  
when it shouldn't, and falling back on whitespace splitting.  Now  
that first part can match whitespace optionally mixed with a single  
autocall esc char.

This, um, fixed the problem, though I wouldn't swear as to *how* (see  
note about full rewrite above).
