I don't understand what you are asking for, because the names
already make no difference to the indentation of subsequent lines.

Compare the result of indenting:

do i = 1, 10
foo
end do

and

very_long_label: do i = 1, 10
foo
end do

Lines 2 and 3 get the same indentation in both cases.

What you seem to be asking for is the option to indent named statements
to column 0. That's probably doable, but it won't be a high priority.

I'm not going to implement this. It is too difficult to support
constructs split across lines.
