I don’t understand how this diff relates to the commit message. Whether PASS contains a space or not, using its expansion and deleting its first line are two quite different things.

I fixed in upstream (https://gitlab.com/alfix/bsddialog/-/commit/ce220b82ad546d3518a805750e5ee6add73f1fbf) because the problem also appears in other places in this file. I'll test and import the new version 1.0.3 by 2-3 days.

I would rather filter the output from bsddialog so PASS never contained the SSID in the first place.
