Still present in devscripts 2.26.9. The original test case and the nested-quote variant
. "$(realpath "${config_file}")"
both still trigger "sourced script with arguments", although no
argument is passed to "." in either. The variant occurs in the wild
in distrobox-enter (line 137).
Disclosure, encouraged by Debian GR 2026-002: this follow-up was
drafted with AI assistance; the reproducers were verified by me
against checkbashisms 2.26.9.
