In the section documenting `@pxref` there is the following paragraph.
In past versions of Texinfo, it was not allowed to write
punctuation after a ‘@pxref’, so it could be used _only_ before a
right parenthesis. This is no longer the case. The effect of
‘@pxref{NODE-NAME}’ is similar to that of ‘see @ref{NODE-NAME}’.
However, in many circumstances the latter is preferable, as this
makes it clear in the Info output that the word "see" should be
present.
I don't understand what the last sentence means; please elaborate. As
far as I understand the issue, `see @ref{}` should be avoided for the
sake of Info output. In other words, it is better to write
```
Foo equals bar; @pxref{This} and @ref{That}.
Foo equals bar; @pxref{This}.
```
to get
```
Foo equals bar; *note This:: and *note That::.
Foo equals bar; *note This::.
```
What am I missing?
