Your message formatting was all messed up, but I can see that you are
still subtracting VARHDRSZ - don't do that: VARSIZE_ANY_EXHDR already
has the header size subtracted (hence "EXHDR"), it returns only the data
size. (The header size is variable, 1 or 4 bytes, so it wouldn't make
sense to include it.)
