This used to exit immediately, leaving the sleep process running in the

response to any bug (real or not) in bash.
I'm not suggesting it's a bug in bash. If anything it's a bug
in the script.
Keep in mind, that the timedated script is not the only affected script,
there is at least src:fence-agents as well and there might be other
packages affected as well as local scripts which expect /bin/sh to
behave POSIX compliant in that regard.
If this change in behaviour is kept, I would at least expect a big fat
NEWS entry in the Debian dash package which is shown on upgrades and it
should probably also update the package description which currently
still says that it is a POSIX-compliant shell.
