BASH_SUBSHELL isn't complicated at all.  It's just documented in a
confusing way.  It doesn't require an example to say that it reports the
current subshell depth.  It's just that the existing documentation
can be interpreted to make someone think that it tracks a running total
of how many subshells were created as children of the current shell in
the past.  That's where Sam got mixed up.
