How to indent entire section heading and indent second line, if it comes, further

Question

I am formatting my CV in latex, and I currently have all my section headings indented by 2em. The first item is the date of the \NewEntry and after that I have \hspace{1.5em} inserted to separate the date from the position field. However, some of my position titles are longer than one line. As such, the second line conforms to the 2em indent that applies to the entire heading (meaning it is aligned with the date). But what I want the second line to do, should it come, is to conform to the beginning of the position title (i.e. \hspace{1.5em} after the date entry. So, essentially, I want an indent within an indent, or something of that nature.

Note: If I manually enter an \hspace into my position title where I want the second line text to indent, which is an annoying solution anyway, no change results.

Here is the code I am using:

\documentclass{scrartcl}

\reversemarginpar 

\newcommand{\MarginText}[1]{\marginpar{\raggedleft\itshape\small#1}} 

\usepackage[nochapters]{classicthesis} 
\usepackage[LabelsAligned]{currvita} 
\usepackage{color}

\usepackage{hyperref} 

\newlength{\datebox}\settowidth{\datebox}{Spring 2011} 

\newcommand{\NewEntry}[3]{\noindent \hangindent=2em\hangafter=0 \parbox{\datebox}{\small \textit{#1}}\hspace{1.5em} #2 #3 
\vspace{0.5em}} 

\begin{document}
\thispagestyle{empty}

\begin{cv}

\NewEntry{2013}{Research Fellow, Ronald McDonald International Fellowship, Institute of Multidisciplinary Education} 

\end{cv}
\end{document}

Here is how this looks:

2013     Research Fellow, Ronald McDonald International
Fellowship, Institute of Multidisciplinary Education

Here is how I want it to look:

2013     Research Fellow, Ronald McDonald International
         Fellowship, Institute of Multidisciplinary Education

*Keep in mind that this entire section is already indented 2em. In addition, I want to indent Fellowship 1.5em (as shown in the immediately above example).

Answer 1

This might be a start:

\documentclass{scrartcl}

\usepackage[nochapters]{classicthesis} 
\usepackage[LabelsAligned]{currvita} 

\newlength{\datebox}\settowidth{\datebox}{Spring 2011} 

\newcommand{\NewEntry}[3]{%
  \parshape 1 \dimexpr 3.5em+\datebox\relax \dimexpr\textwidth-3.5em-\datebox\relax%
  \noindent\makebox[0pt][r]{\makebox[\dimexpr 1.5em+\datebox][l]{#1}}%
  #2 #3
}
\vspace{0.5em}} 

\begin{document}
\thispagestyle{empty}

\noindent \rule{2em}{1pt}

\begin{cv}
  \NewEntry{2013}{Research Fellow, Ronald McDonald International Fellowship, Institute of Multidisciplinary Education}{ABC}
\end{cv}

\end{document}

\NewEntry is set using \parshape 1 <indent> <width>, which changes the shape of the entire paragraph. Each line will be indented by <indent> and have a width that spans the remainder of the line. adjustwidth from changepage would also have worked here.

The \rule is meant to highlight the fact that the date is indented by 2em.
