There are 4 different ref commands, all with slightly syntactic
requirements and outputs when compiled using makeinfo.  I for one use
@pxref{} a lot, and it has different requirements for placement than
@ref or @xref (namely those two MUST have a . or , following the end
of the ref)

Not entirely true, @ref{} will add a period after the end of the reference in the info output
if no period or comma present, @xref{} needs a comma or period.  @pxref{} can be
followed by a period, comma or right parenthesis, otherwise the info output will include
a period as well.

So all three must have some sort of punctuation (or paren) following them to ensure that
the references are clearly delimited.

8.1 Different Cross Reference Commands
There are four different cross reference commands:
@xref Used to start a sentence in the printed manual saying ‘See . . .
’ or an Info
         cross-reference saying ‘*Note name : node.’.
@ref Used within or, more often, at the end of a sentence; same as
@xref for Info;
    produces just the reference in the printed manual without a preceding ‘See’.
@pxref Used within parentheses to make a reference that suits both an
Info file and a
        printed book. Starts with a lower case ‘see’ within the
printed manual. (‘p’ is
               for ‘parenthesis’.)
@inforef Used to make a reference to an Info file for which there is
no printed manual.

(from the Texinfo manual)
