    devhelp: ignore trailing symbol characters
    
    We might get a symbol name like "foo(Bar *self)" and we can only reliably
    search for "foo". So strip everything starting from (.
    
    In the future, we should add symbol get_type_name() so that we can search
    for that instead of the display name in IdeSymbol.
