I guess stsp uses vim:

===> regress
===> regress/cmdline
==== checkout ====
./checkout.sh -q -r "/tmp"
./checkout.sh[1208]: xxd: not found

That's in test_checkout_bad_tree_entry.  xxd is part of vim and not
generally available.  Since doing this in a portable way seems to
be surprisingly difficult[1], maybe another approach is possible?


[1] My attempt with awk so far:

function h2d(x) {
        return index("0123456789abcdef", tolower(x)) - 1
}

{
        for (i = 1; i < length($0); i += 2) {
                c = h2d(substr($0, i, 1)) * 16 + h2d(substr($0, i+1, 1))
                printf("%c", c < 128 ? c : c - 256)
        }
}
