label pseudobonds doesn't work if given pbond model number

[Elaine Meng]

I'm pretty sure this used to work, but now the following doesn't show the labels:

open 1zik
hb rev t salt t
label #2 pseudobonds

...where #2 is the hydrogen bonds pseudobond model, although "label hbonds pseudobonds" will work. When I found this problem, I didn't want to use the hbonds specifier because in my case I had two pseudobond models and wanted to label the one named "salt bridges", not the one named "hydrogen bonds".

Currently the label command recognizes only atoms specified by its argument.  I agree that should be changed to handle pseudobond group specifiers too.

Fixed.
