what it prepends instead of the result of getcwd(3), about which posix
says:

imo it would be nice if it *did* prepend $PWD, that feels like the
expected thing. in the past i've just done that myself where it matters,
and it seems to work in the common case:

  [[ $dir == /* ]] || dir=$PWD/$dir
  dir=${dir:a}

but i think there are some other cases where $PWD itself is not what
you'd expect? not sure
