I am aware of that.  I don't see what you mean by that comment given
the question and how it's relevant.

"trap -- - HUP" means the disposition for HUP is SIG_DFL, which is
suprising, given that nohup makes it ignored.

bash that reports "trap -- '' HUP" tells that the disposition for HUP
is SIG_IGN, as expected under nohup.
