Control-flow indented code

[bquistorff]

Is there anyway to write the smcl so that indentations inside code are respected? For example,

if (a) {
    di "hi"
}

I couldn't get anything but phang2 to show up as code (not e.g. phang3) and raw tabs or {tab} didn't seem to work either. Also, was a period "." required to get it show the pre block?
