Thanks, that's how I assumed it would look.

Do you want to add any more documentation ?  

Few more things:

You refer to as "stdin" any filename beginning with -.

I think you could just print "-" and not "stdin".
In any case, *filename=='-' is wrong since it only checks filename[0].
In a few places you compare ==stdin (which is right).

Also, I think "f" isn't as good a name as "fp".

You're adding 139 lines to a 600 line main(), and no other option is more than
15 lines.  Would you put it in a separate function ?
