In 6aec8d38fdd (t: refactor tests depending on Perl to print data,
2025-04-03) we have changed some of the tests in t4150 to use sed(1)
instead of Perl. One of the conversions is broken though:
sed: -e expression #1, char 41: unterminated `s' command
Curiously enough, the test itself still passes. This is caused by a
sequence of failures:
1. The output of sed(1) is piped into git-update-ref(1), and because
sed(1) is the upstream command we don't notice that it fails.
2. git-update-ref(1) does not receive any input and thus won't create
any references.
3. We then repack the repository with the configured pseudo merges
pattern, but as we didn't create any references the pattern doesn't
match anything.
4. We use `test_pseudo_merges()` to compute the list of pseudo-merges
and write it into a file. This file is empty as there are none.
5. The loop over the pseudo-merges becomes a no-op.
6. The final test succeeds as well because the number of lines in an
empty file is obviously the same as the number of unique lines,
namely zero.
Fix the issue by adding the terminating '|' to the sed(1) command.
Furthermore, make the test a tiny bit more robust by not using it as
part of a pipe.
