Rewrite the loop that handles substitution in the -I case, and try to make
it easier to understand.  Making it easy to understand isn't all that easy,
so litter the code with comments so some other poor soul can come along some
day and work on this if they see fit to do so.  Avoid calling strlen(3) to
check for a nil-string, when we can just check for *str=='\0'.
