Thanks for this, your git-fu is much stronger than mine! 

I wonder why the mutator func for d_nitems didn't make it into the current version. At least for me, it's really useful to have.

Anyway, looks like it won't be too bad to graft in. Thanks again.

Taking a quick look at a branch of that hash tag, the Reset function simply sets d_nitems = 0.  There are 4 helper functions within the Skip Head block of old that are not in the current one; namely setting the number of items to skip, checking how many items are to be skipped, checking how many items have currently been skipped, and resetting the block.  The code below is from the hash tag given, and should be trivial to implement into the current block (the variable names are even still the same).

gr_skiphead::set_nitems_to_skip(uint64_t nitems_to_skip)
  d_nitems_to_skip = nitems_to_skip;

gr_skiphead::nitems_to_skip() const
  return d_nitems_to_skip;

gr_skiphead::nitems_skiped() const
  return d_nitems;

  d_nitems = 0;

that commit is in master. Note that it's old, and committed *before* the
3.7 API change, so the changes are moved to the corresponding new block
in gr-blocks.
