I don't understand what this error message means, in terms of the
Texinfo sources.  Can you explain, please?  Taken at face value, it
looks like a bug in TeX.pm, whereby a variable is not initialized.

These all seem bogus, because the source looks correct to me.  Here's
the first instance:

  @end html

I see nothing wrong here; do you?

(Maybe you are using an old version of the manual; I looked in what's
currently on the emacs-26 branch of the Emacs Git repository.)

Nothing wrong here, either:


  @item @strong{Whenever an IDL error occurs or a breakpoint is hit, I get
  errors or strange behavior when I try to type anything into some of my
  IDLWAVE buffers.}

The Texinfo manual says it's okay to have multi-line text after @item:

     Write the text of the enumerated list in the same way as an itemized
  list: write a line starting with '@item' at the beginning of each item
  in the enumeration.  It is ok to have text following the '@item', and
  the text for an item can continue for several paragraphs.

Looks like po4a doesn't support this feature of the Texinfo language?

Hard to do anything with this, without more diagnostic data.

These looks bogus as well.  E.g.:

> cmdargs.texi:726: (po4a::tex)
> unmatched end of environment 'vtable'

There's a matching "@vtable @env" on line 674.

So I submit these problems are bugs in po4a, and the Emacs manuals are
