Log message:
head(1): refactor main loop
The main loop here is horribly obfuscated. In particular, the path
through the loop to exit(3) is very complex.
Refactor the open/read/write/close portions of the loop out of main()
into a separate function, head_file().
The result is a lot easier to understand at a glance. In particular,
the path to the end of main() is now dead simple.
