I like this idea (and certainly, I've had need for it.).
I get the impression that PDB  function signatures are not intended to be
changed so often, because of the compatibility issues it could cause.

However, it's exactly the PDB interface to this that I'm most interested in.
Maybe you should make a variant named by-color-select-full, it could include
also the control of whether to select transparent areas, which I've found
very important (and the lack of it is somewhat difficult to work around).
If you do, then also make a corresponding fuzzy-select-full.

*trying it now*
Okay, hunk #2 of the patch to selection_tools.pdb failed, so I applied it
manually.
Not sure why it failed.

..gimp_channel_select_fuzzy and gimp_drawable_bucket_fill_full should also
have the select_criteria parameter added; gimp_contiguous_region_by_seed
seems to support it.

Addressing the above would satisfy me as to this patches' quality. For more
completeness, you could also add a set of radiobuttons arranged horizontally
under the main SelectionEditor display ('r','g','b','h','s','v','*') to
change between the different selection criteria usable when operating it.

My comments on the UI will follow, after I recompile.
