Michael pointed out that bones will never occur while swallowed because
makemon of the ghost will always fail. I suggested that the outcome made
sense, since your body may be digested, torn apart, whatever. But, there
was no explicit check for this to make it obvious this was occuring.
Pat added some error information to create_levelfile.
This does the same for create_bonesfile, but the
only place it is logged is in the paniclog, unless
you're in wizard mode. If bones file creation is
silently failing for someone and they aren't getting
bones files, this provides a way to diagnose why.
Update the other trickery situation. I don't know how I managed
to miss this. The disadvantage of suppressing extern.h from normal
dependencies I guess.
