I should have pointed that out. Sorry. I did remember to say the
continuations weren't there, and I thought the comment text was pretty
obvious. The layout I used was to try to explain how the item worked,
not to make it look pretty. It's hard to make this stuff look pretty. :-)

Note, however, that leading whitespace *is* ignored after a
continuation. So if you write an option such as
xxx = ${sg{\
${readfile{/file}{|}}\
}\
{\\|(\\||\$)}\
{$1}\
}
The space in front of ${readfile would *not* be significant. I guess
that's why I didn't bother to mention this point.
