indentation

Hi!

Say I have the following template:

void foo(int a)
{
    int i = 0;
    $do_something
    for (i = 0; i < 10; i++) {
        $do_something
    }
}

This works just fine if $do_something consists of a single line;
however, if $do_something consists of multiple lines, then I have a
problem with the indentation, depending on what exactly the
placeholder itself looks like:

1) if the placeholder does not include any indentation itself, then
the first line is indented correctly (because the indentation appears
outside of the placeholder), but the rest are not;
2) so, I could have the placeholder already include the indentation,
but this has two problems:
  (a) the placeholder would have to appear unindented in the template,
which is not pretty; and
  (b) more importantly, the placeholder may appear in multiple places,
each requiring different indentation.

I'm aware of the "undocumented" #indent function (as documented in the
TODO), and by playing around with it (using cheetah 2.4.4) I see that
some of the options work, and am able to get the indentation correct.
However, I'm a little wary of using undocumented features which may be
in flux; and also, the resulting templates are much more verbose than
I would like (too many #indent commands).

Ideally --- what seems to me like the natural solution (without having
considered use-cases that are different than mine, and without having
looked at the implementation at all ;) ) --- I would like the
indentation of a placeholder to be added to each line of the
placeholder's contents. Is that possible / difficult to implement /
inappropriate for other use-cases? Does anyone have any other
suggestions for achieving what I want?

Thanks!
Dov
