Cast to uschar when storing a char in an int that will be used as an index (#88)
* Cast to uschar when storing a char in an int that will be used as an index.
Fixes a heap underflow when the input char has the high bit set and
FS is a regex.
* Add regress test for underflow when RS is a regex and input is 8-bit.
