Subject: The .subn() method wasn't setting _num_regs, which is used by the .groups()
X-Git-Tag: v1.5.2a2~364

The .subn() method wasn't setting _num_regs, which is used by the .groups()
	method, so .groups() didn't work inside the replacement function
	called by re.sub.  One-line fix: set self._num_regs inside subn().
