manual on tex-dvi-view-command default value

[Kevin Ryde]

I see tex-dvi-view-command has a reasonably sensible default value
these days (choice of xdvi, dvi2tty or yap), so I think the manual
needn't to say you have to set it.

        * text.texi (TeX Print): tex-dvi-view-command has a default value,
        remove the bit saying you must set it.

Of course whether the default is a program you've got and like is
another matter, so the "may (or may not)" qualifier better stay. :)
