Bash does NOT ignore "set -e" here; it just sets "set +e" in the
command substitution subshell.  You can see this by reenabling
"set -e" inside:

	$ ./bash -ec 'echo "$(set -e; echo a; false; echo b)"'
	a

Compare with a context in which it actually does ignore "set -e":

	$ ./bash -ec '! echo "$(set -e; echo a; false; echo b)"'
	a
	b
