Well it is either

 * the sed magic is so arcane that you'd need to spend a long time,
   comparable to 2 hours you already spent, if you ever need to look
   at it and figure out what it does next time you need to change
   something in it.

or

 * you are not familiar with the sed magic and you would be able to
   write the same thing in 2 minutes next time if you need to adjust
   it when we add -pid back later.

Either way, those 2 hours are not wasted.

I personally fall into the former category.  Any sed script that
needs G, h, and x together I need to spend at least 15 minutes just
to warm myself up, as I do not work with the language that often.

Thanks ;-)
