Fix unportable usages of tolower(). On signed-char machines, it is necessary
to explicitly cast the output back to char before comparing it to a charvalue, else we get the wrong result for high-bit-set characters. Found byRolf Jentsch. Also, fix several places where <ctype.h> functions were beingcalled without casting the argument to unsigned char; this is likewiseunportable, but we keep making that mistake :-(. These found by buildfarmmember salamander, which I will desperately miss if it ever goes belly-up.
