It looks complicated:
$ if false; then :; fi | true; echo ${PIPESTATUS[*]}
0 0
$ if false; then :; fi | true; echo $?
0
$ if false; then :; fi ; echo ${PIPESTATUS[*]}
1
$ if false; then :; fi ; echo $?
0
I'm sure there's an explanation, but I'm not feeling up to spelunking
through the documentation enough to figure it out.
