Re: tbl/eqn: # does not work as delimiter

[Michael Cain]

The tbl preprocessor makes extensive use of the # character, including  
creation of a macro named T#.  When instructed to do so, the eqn  
preprocessor subsequently picks these up as delimiters, and then  
complains about the contents, as well as creating mangled things to  
pass on to groff.  Under some circumstances, tbl may use other special  
characters in names as well. All of $, % and @ appear to be safe  
delimiters when placing equations in a table.
