Snippet from compile is confused. (the last period)

The optional arguments flags and dont_inherit control which future statements affect the compilation of source. If neither is present (or both are zero) the code is compiled with those future statements that are in effect in the code that is calling compile(). If the flags argument is given and dont_inherit is not (or is zero) then the future statements specified by the flags argument are used in addition to those that would be used anyway. If dont_inherit is a non-zero integer then the flags argument is it – the future statements in effect around the call to compile are ignored.

Fix an uninitialized bool in exception print context.
    
`struct exception_print_context.need_close` was uninitialized.

Pretty obvious what the ommission was upon code inspection.
