I suggest adding a second value to the text-indent property
that indents every line.

p.indent {
  text-indent: 2em; /* same as "text-indent: 2em 0;" */
}

p.sub {
  text-indent: 0 2em; /* indents the whole paragraph 2em */
}

p.hanging {
  text-indent: -2em 2em; /* hanging indent of 2em */
}

The above could be defined as shorthand for two new properties
 text-first-indent: <length> | <percentage> | inherit
 text-block-indent: <length> | <percentage> | inherit

 text-indent: <'text-first-indent'> <'text-block-indent'>? | inherit

Indentation is always on the starting side of the text.
(left for ltr, right for rtl)
