This directive is not implemented yet. When/if it's completed, it will allow you to
#ifblocks) without affecting the output
There is some experimental code that recognizes the
directive with options, but the options are purposely undocumented at this

and would like to see it implemented sooner rather than later, let us know
on the mailing list.
The latest specification for the future
#indent directive is in the
TODO file in the Cheetah source distribution.
