Hello,

When exporting the following Org file to Texinfo:

    - Function: foo_bar arg ::
      Contents.

The part after the underscore is completely skipped:

    @defun foo
    Contents.
    @end defun

And, if I export it to HTML, the `bar' part is shown as a subscript, and
I don't know if it's intended:

    <dt>Function: foo<sub>bar</sub> arg</dt>
    <dd>Contents.</dd>

Another small detail, which might not be important, is that when
exporting to HTML, the description of the function is only wrapped in
<p> tags if it has more than one paragraph. This kind of makes sense,
but results in inconsistent spacing when multiple functions are close:

    Here's a list of functions:
    - Function: foo arg ::
      This has multiple paragraphs.

      Another paragraph.
    - Function: bar arg ::
      Just one line.
    - Function: baz arg ::
      One line, again.
    Here's some text after the list.

This is not a huge issue, since the user can just add some CSS (which I
personally use in my blog):

    dl.org-dl dd p:nth-child(1) {
        margin-top: 0px;
    }

    dl.org-dl dd p:nth-last-child(1) {
        margin-bottom: 0px;
    }

Thank you.

Fixed, on main.

This is intended. _ is syntax for subscript in Org markup.
See https://orgmode.org/manual/Subscripts-and-Superscripts.html
That section of the manual also talks how to modify export behavior wrt
sub/superscripts if you need to use underscore often.

Wrapping into <p> is intentional. Not doing it will break other
scenarios...

However, see https://list.orgmode.org/orgmode/875ydracnq.fsf@localhost/
There are some cases when <p> is indeed creating awkward rendering. But
I have no idea what we can do.

It would be nice if someone with better HTML-foo chimed in with ideas.
