Indenting only subsequent lines in paragraphs in LaTeX

In order to remove the indent at the beginning of paragraphs, and indent subsequent lines if present, add the following to your preamble:

\newcommand{\hangpara}{
 \setlength{\parindent}{0cm} % don't indent new paragraphs
 \hangindent=0.7cm % indent all subsequent lines
}

Then add \hangpara before each new paragraph, for example:

\hangpara
The quick brown fox jumps over the lazy dog.

\hangpara
The quick brown fox jumps over the lazy dog again.
