[texinfo.tex 2023-03-13.20] Consider the following snippet.
```
\input texinfo
@findex{foo}
@code{foo},
@findex{bar}
@code{bar},
@findex{baz}
@code{baz}
@bye
```
This no longer works as expected – with version 2022-12-19.22 the
output is OK (I didn't bisect to find the exact last working version,
though).
