@xref seems to be generating lowercase "see" for me, perhaps because I'm
using makeinfo 4.13?  I'll change to @ref anyway.

Hmm, maybe rephrasing like this:

    @defun add-variable-watcher symbol watch-function
    This function arranges for @var{watch-function} to be called whenever
    @var{symbol} is modified.  Modifications through aliases
    (@pxref{Variable Aliases}) will have the same effect.
