[PATCH 5/8] Avoid shellcheck warning

shellcheck warns:
Avoid x-prefix in comparisons as it no longer serves a purpose.

While this is true, it also does not really harm - besides some
arguments about readability. As zsh fixed this only ~11 years ago, let's
keep it for some years but silence shellcheck.
