_REWRITE_CAPHI_RE_4 = re.compile(u'u\\_w-\\+([^iau]+|$)')

Hello,

This CAPHI rewrite rule seems to be broken. I changed to u'u\\_w-(\\+[^iau]+|$)' and fixed it by moving the \\+ to inside the optional group as it will generally be coming from a suffix and should be treated as optional. Tested the new regex on PATB and it is giving the required results.
