It may have been painful, but personally I think it's still the right
way to do it.  Of course, that's a pretty easy thing for me to say,
since you're pretty far ahead of me and I haven't felt your pain yet.
Maybe I'll change my mind after trying it for a while, but I'm not
convinced just yet.

Should the second word of the second paragraph be 'fd' rather than another 'if'?

My compiler complains that you didn't typecast the return value from
strlen to an int.
