set: -E: unknown option error on OpenBSD

[morgant]

When attempting to run roundup on OpenBSD (6.5-release, in my case), one receives the following error:

./roundup[307]: set: -E: unknown option

This is because /bin/sh on OpenBSD does not support the -E option, only the -e option.

/bin/ksh doesn't support the -E option either, so it'd be best to use bash on OpenBSD (which is available in ports).
