Thanks, I added that to the description. It means that bash versions
later than 4.0 interrupt a list when one of the commands in the list
terminates due to SIGINT and job control is in effect; previous versions
just continued on.

There is only a single shell compatibility level; the last variable
set wins. The compatibility level variables are mutually exclusive.
The descriptions of each option are self-contained. That's why the
descriptions for compat32 and compat40 include the same text concerning
using strcoll for < and > comparisons (and why the description for
compat31 should include it as well).
The COMPAT file in the bash distribution has a much more extensive
description of incompatibilities between versions.
