[Bug-tar] 1.16.1: T-null.at vs. echo backslash interpretation

[Christian Weisgerber]

The T-null regression test erroneously fails on OpenBSD (and probably
some other platforms as well).  The problem is that the expected
output string

...
[jeden\ndwa
trzy
],
...

is passed on to the echo(1) command in the generated testsuite script:

echo >>"$at_stdout"; echo "jeden\\ndwa
trzy
" | $at_diff - "$at_stdout" || at_failed=:

The builtin echo command of OpenBSD's sh performs backslash
interpretation by default, producing

jeden
dwa
trzy

instead of the expected

jeden\ndwa
trzy
