[tex-k] Web2C: "-parse-first-line" does not work in on-line fileprompt.

On page 26 of TeXbook it is said that "tex &plain story" loads the plain
format before inputting the "story" file. But terminal log says that
"tex" format is loaded:

$ tex -ini '\input plain.tex \dump' >/dev/null
$ tex \&plain story
This is TeX, Version 3.14159265 (preloaded format=tex)
(/usr/share/texlive/texmf-dist/tex/plain/knuth-lib/story.tex [1])

Is it possible to check what would be output by non-web2c TeX?

The original example is garbled in mailing list archives.
This is the same example, using only ASCII:

    echo -e '%&lhplain\n\xD1\x8B\\bye' >test.tex
