Indented regions in ms (The GNU Troff Manual)

#### 4.6.5.7 Indented regions

You may need to indent a region of text while otherwise formatting it normally. Indented regions can be nested; you can change `\n[PI]` before each call to vary the amount of inset.

Macro: `.RS` ¶

  Begin a region where headings, paragraphs, and displays are indented (further) by the amount stored in the `PI` register.

Macro: `.RE` ¶

  End the (next) most recent indented region.

This feature enables you to easily line up text under hanging and indented paragraphs. For example, you may wish to structure lists hierarchically.
