Replying to [comment:22 jdemeyer]:
> Leif: what do you think of this alternative patch? I've tested that it
behaves the same as `set -o pipefail`.
Better. :)
Using `eval` twice still behaves different to what you get directly on the
command line; we could instead use:
{{{
#!sh
eval "$1 | $2 ; ecs=(\${PIPESTATUS[*]})"
if [ ${ecs[1]} -ne 0 ]; then
exit ${ecs[1]}
else
exit ${ecs[0]}
fi
}}}
The comment ''"Like this, ..."'' is a bit misleading, as we exactly fix
that undesired behavior with `pipestatus`.
