Similarly, comments do not necessarily have a "tidy" place they can be printed in such a circumstance. Forbid this usage by renaming "suppress_first_indent" to "dict_value" to emphasize that indents are suppressed only for the benefit of dict values; then add an assertion assuring we do not pass ifcond/comments in this case.
