Control tokens like \4 in CWEB

Indeed, "@t stuff @>" puts "stuff" in WEAVE's TeX output (wrapped in an
\hbox{}). '\4' means "backspace one notch".

The TeX macros \1..\7 come fairly early in 'webmac.tex'. (Pascal WEB 
does not know of \8 and \9; these are defined in CWEB's 'cwebmac.tex'.)

Happy WEB programming!
