Allow a space after __except
Allow a space after __except

__except () is the canonical layout for code that uses __try/__except,
Microsoft's structured exception handling. The majority of __except
uses in our code use a space after the keyword. However cpplint.py
thinks that __except is a function name. Apparently we have been forcing
this through by ignoring the presubmits. This just adds __except to the
list of exceptions to the whitespace/parens rule.
