[PyQt] Possible small bug in docstring generation

[Shaheed Haque]

Hi Phil,

With sip 4.18.1, I noticed this function:

KMIME_EXPORT bool parseGenericQuotedString(const char *&scursor,
        const char *const send,
        QString &result, bool isCRLF,
        const char openChar = '"',
        const char closeChar = '"');

ends up generating a docstring as follows, which of course is missing
any escaping of the quotes...

PyDoc_STRVAR(doc_KMime_HeaderParsing_parseGenericQuotedString,
"parseGenericQuotedString(str, str, str, bool, str = '"', str = '"')
-> bool");


I'm not sure if this is fixed in a more recent release, but I thought
it worth mentioning...

Thanks, Shaheed
