lo-regexp.cc: prevent cast of negative floating point value to size_t.
* regexp.cc: simplify two expressions like "static_cast<size_t> (e - 1) + 1"
to "static_cast<size_t> (e), where 'e' is a nonnegative index value of type
double. This prevents a cast of -1.0 to the unsigned integral type "size_t"
whenever 'e' is zero. A test case where this occurs (for the second change) is
regexprep ('World', '^', 'Hello ', 'emptymatch').
