Use a line length of 1.6 inches. By the way: instead of \h'0' you can also use \v'0', \X'', or probably a lot of other things that put "something else" in the output. By the way 2: instead of setting a register to the current horizontal position, you could also trigger a break (.br) and then use register .n (length of text portion on previous output line).
