Mark is correct, at least for recent versions of GCC.  strlen of a
constant string without embedded zeros is folded to sizeof the string
minus one.

If it makes the code harder to read, I do object.  This, and similar
motifs with hardcoded lengths instead of duplicated strlens, are all
through that file.  I was careful to keep the duplications close
together so that they are easily visually confirmed.  I don't want to
have to hunt around for the code implementing a particular packet.

If it makes the code easier to read somehow, I don't object - I'd
have to see it.
