Regex Fails to Match

[BenHanson]

using namespace ctpg;
using namespace ctpg::buffers;

constexpr char number_pattern[] = "0|[1-9][0-9]*";
constexpr ctpg::regex::expr<number_pattern> r;
const bool match = r.match(string_buffer("0"));

match returns false, whereas matching string_buffer("1") returns true.

Unfortuantely confirmed. Easy fix. This is a regression introduced when changed regex parser to have a handcrafted lexer. A corner case was added and no unit test covered it. Already have a fix.

Should be fixed now. Added appropriate unit test.

Thanks! Will test now.
