[texhax] 'continue to next line' control sequence?

[Bryan W. Lepore]

does latex or tex have a 'continue to next line' control sequence? 
something like \ in gnuplot?

e.g., i have some really long lines in table, (modulo your email program's 
word-wrap):

&\%something$\to$&\multicolumn{1}{|c|}{5\%}&\multicolumn{1}{|c|}{10\%}&\multicolumn{1}{|c|}{13\%}&\multicolumn{1}{|c|}{14\%}

i'd like to make it something like :

&\%something$\to$&\multicolumn{1}{|c|}{5\%} CONTINUE-TO-NEXT-LINE 
&\multicolumn{1}{|c|}{10\%}&\multicolumn{1}{|c|}{13\%}&\multicolumn{something}

so its easier in emacs.
