Fix tail option problem in test

The tail command on my system complains:

tail: cannot open `8192' for reading: No such file or directory

if there is any whitespace between the '-c' option and the byte count.

I do not like using tail to do a byte-oriented thing like this to begin with. How about using the plain old trustworthy and portable program, "dd", instead?

It's not as easy to get the last X bytes of a file with dd.
