I found this in git bisect:

              printf >&2 'Are you sure [Y/n]? '
              case "$(read yesno)" in [Nn]*) exit 1 ;; esac

which looks very weird since read(1) returns a status and not the
string reads from std input.

Am I missing something ?

Yes.  "$()" does not return the status, but the output.

But there is no output, since read doesn't print anything...
case "$(read yesno; echo $yesno)" in [Nn]*) could work, but looks
a bit strange. read yesno; case $yesno in [Nn]*) would be the usual
way to do things i think?
