cartoon style command interprets spec with atoms but without biopolymer residues as "coil"

[Elaine Meng]

I am prototyping possible presets and noticed that in certain cases "cartoon style" interprets a non-ribbonable spec as "coil" which is not good For example

open 2gbp
cartoon style ligand thick 2
... makes all the coil sections fat.

You might say "that's dumb, who would do that"? Well, my actual use case was prototyping possible cartoon-related presets with multiple test structures, and this case took me forever to figure out what was happening:

open 4hhb
cartoon style (nucleic|strand) x rectangle

This makes all the coil have rectangular cross-section because 4hhb has no strand, and although it appears to have no nucleic, there are two (non-polymer, non-ribbonable) PO4 residues incorrectly classified as nucleic.

So now that I understand what it's doing, it should do the right thing and not change the coil if I don't specify any coil atoms (and spec isn't blank).

Eric just fixed the 4hhb PO4 incorrect classification, at least, so perhaps the problem will be rarely encountered.

apparently fixed, including the 2gbp example
