 For the format `m', the optional argument give the length of the string to
 encode (multiple of 3). If it's <= 2, ruby use the default value of 45

 ["abcdefghi", 2, 3, 4, 5, 6].pach("m*) <==> ["abcdefghi"].pack("m6")
 ["abcdefghi", 2].pach("m*) <==> ["abcdefghi"].pack("m2")

pigeon% irb
irb(main):001:0> ["abcdefghi"].pack("m6")
"YWJjZGVm\nZ2hp\n"
irb(main):002:0> ["abcdef"].pack("m")
"YWJjZGVm\n"
irb(main):003:0> ["ghi"].pack("m")
"Z2hp\n"
irb(main):004:0>
