Sorry for the confusion. I meant the number of lines tail is told to
output.

See Isaac's replies in this topic. The current condition is just wrong:
$ cat toys.h toys.h toys.h | tail | wc -l
9
This is fixed with the patch. However in some situations it still gives
wrong output since other code still assumes that there are newlines at
the end of each sizeof(toybuf) piece. Maybe it's simpler to rewrite this
part...
