Strange formatting of literal block in bc(1) man page

[Paul Goyette]

I just happened to notice the following discrepancy.  The literal
block in the man-page source reads as

        For example, consider the following session.
        .Bd -literal -offset indent
        define py (y) { print "--->", y, "<---", "\n"; }
        define void px (x) { print "--->", x, "<---", "\n"; }
        py(1)
        --->1<---
        0
        px(1)
        --->1<---
        .Ed

Note that the two function definitions have a "\n" at the end of the
line.  When formatted by man(1) command we find it rendered as

     ...
     name.  For example, consider the following session.

           define py (y) { print "--->", y, "<---", "0; }
           define void px (x) { print "--->", x, "<---", "0; }
           py(1)
           --->1<---
           0
           px(1)
           --->1<---
     ...

Now the \n in the function definition is shown as "0 and attempting
to use what is shown as an example results in bc syntax error!  :-)

Is there some misssing additional quoting needed in the .1 file?  We
should at least strive to ensure examples actually work!
