Misreport TODO on a string containing 'XXX'

[jianingy]

We have a string literal like, shirt_size = 'XXXL' or shirt_size = 'XXXXL', which been reported as TODO entry.

I would be nice if flake8-todo can ignore string literals.

Thanks

Similar issue with next code:

    customer_postal_code = models.CharField(
        _('customer postal code'),
        max_length=5,
        validators=[RegexValidator(regex=zip_regex, message=_('Enter a zip code in the format XXXX.'))],
    )

Reported line next line: validators=[RegexValidator(regex=zip_regex, message=_('Enter a zip code in the format XXXX.'))], as TODO entry.
