The problem appears to be in make_openout_test () with

eval "$tex_cmd" >/dev/null 2>&1

When changing this line to

echo before eval
echo "$tex_cmd"
eval "$tex_cmd" >/dev/null 2>&1
echo after eval

we have

$ ./texi2dvi test1.tex  
before eval
latex --file-line-error </dev/null '
onstopmode' '\input' ./openout.tex

(The newline before onstopmode is there and was not introduced by
accident when pasting into this mail.)

When running with

eval "$tex_cmd"

instead we obtain

before eval
latex --file-line-error </dev/null '
onstopmode' '\input' ./openout.tex
