test: the third backticked word inside an unquoted heredoc

87b720f0 fixed two of these and missed this one, because the detector used
then required the heredoc's delimiter to end the line and this opener has
a trailing space after it. The agent group hung for its whole 600 s budget
again, in the flip leg this time, on a comment that quoted the expect verb
in backticks: in an unquoted heredoc the shell runs a backquoted word as a
command substitution wherever it stands, macOS has an expect program, and
it read the rest of the heredoc as its own script.

Swept again with a detector that matches the opener anywhere on its line
and skips only a quoted delimiter. Every unquoted heredoc body in test/ is
backtick-free. Nothing gates it, which is the third time that has cost a
gate run.
