Syntax error in autocompletion crashes bpython #347
Description
Using the latest bpython-curtsies
What I started with was this line:
re.sub(r'(^\w+Error|^error)',r"blue('\1')",list[-1])Then I realized, wait, I'd like to set line[-1] equal to this expression I wrote out, so I ctrl-A ed back to the front, and started typing line[-1... in front of the expression I had written. Then bpython exploded:
list[-re.sub(r'(^\w+Error|^error)',r"blue('\1')",list[-1])

SyntaxError: unexpected EOF while parsingJust to be clear, I hadn't hit enter yet or anything, I was just in the process of typing.
All you really need to do to reproduce the error is have something like re.search() and then go back to the beginning of the line and type 1
