Why isn't "HH" the same as "H2" in unpack? An example:
print unpack("H2","A"); gives "41" as expected
print unpack("HH","A"); gives "4" as unexpected!
This is with perl version 4.0, Patch level: 3, SunOs 4.1, Sun 3/80

H, h, B and b always align to a byte boundary when they're done. It just
seemed a little silly to keep track of where in the current byte we were,
I guess.
