match returns true even though there is extra input

[dundalek]

See the example, when using regex for validation I would expect .match to match on the whole input, but it returns true even if there is extra input.

Running Zig 0.7.0 and zig-regex from master:

const std = @import("std");
const print = std.debug.print;
const Regex = @import("zig-regex/src/regex.zig").Regex;

pub fn main() !void {
  var re1 = try Regex.compile(std.heap.page_allocator, "ab");
  print("{}\n", .{try re1.match("ab")}); // true, ok
  print("{}\n", .{try re1.match("abc")}); // Expected: false, Actual: true
  var re2 = try Regex.compile(std.heap.page_allocator, "^ab$");
  print("{}\n", .{try re2.match("ab")}); // true, ok
  print("{}\n", .{try re2.match("abc")}); // Expected: false, Actual: true
}
