# Modern versions of ShellCheck now natively support BATS syntax, so
# running the preprocessor ourselves to feed to ShellCheck "should" no
# longer be necessary.  However, as of ShellCheck 0.10.0, it doesn't
# know about --separate-stderr and so emits spurious SC2154
# ("referenced but not assigned") warnings about ${stderr} and
# ${stderr_lines[@]}.  ShellCheck has already fixed this in 796c6bd
# (Add new bats variables stderr and stderr_lines, 2024-04-24), so we
# only need to keep this around until the next ShellCheck release.
