[Tex/LaTex] How to fix verbatim causing an extra newline inside a description list environment

descriptionline-breakinglistsverbatim

I'm trying to create a documentation listing similar to that used by MSDN. Here was my first attempt at that:

\subsubsection{User Default Page URL}
\begin{description}
\item[Rationale] This is the default page displayed to a user when
(s)he opens a new window or tab in Microsoft's Internet Explorer browser.
\item[Data Sources] \begin{verbatim}
[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer]
"Default_Page_URL"="${url}"
\end{verbatim}
\item[Log Format] \begin{verbatim} 
uDefaultPageUrl=${url}
\end{verbatim}
\item[Description] The variable \var{url} is escaped using the URL
escaping scheme defined in \ref{urlescape}.
\end{description}

Which produces:

example output

Of course, this is wrong behavior — the registry key bit needs to go on it's own, not pushed over to the right on the first line. I tried following the instructions on this question, which left this:

\subsubsection{User Default Page URL}
\begin{description}
\item[Rationale] \hfill \\ This is the default page displayed to a user when
(s)he opens a new window or tab in Microsoft's Internet Explorer browser.
\item[Data Sources] \hfill \\ \begin{verbatim}
[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer]
"Default_Page_URL"="${url}"
\end{verbatim}
\item[Log Format] \hfill \\ \begin{verbatim} 
uDefaultPageUrl=${url}
\end{verbatim}
\item[Description] \hfill \\ The variable \var{url} is escaped using the URL
escaping scheme defined in \ref{urlescape}.
\end{description}

producing:

example longer output

This is bad because now there's a huge space before the verbatim text. Also, XeTeX decided to complain quite a bit about bad boxes on this one.

I've tried several "massagings" of this — such as removing the explicit newline after the \hline on Verbatim environments only. That shrinks the space, but not enough — it still looks like a huge gaping hole.

How would one fix this?

EDIT: In response to the comment:

\subsubsection{User Default Page URL}

\begin{description}
\item[Rationale] This is the default page displayed to a user when
(s)he opens a new window or tab in Microsoft's Internet Explorer browser.
\item[Data Sources] \hfill

\begin{verbatim}
[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer]
"Default_Page_URL"="${url}"
\end{verbatim}
\item[Log Format]
\begin{verbatim} 
uDefaultPageUrl=${url}
\end{verbatim}
\item[Description] The variable \var{url} is escaped using the URL
escaping scheme defined in \ref{urlescape}.

\end{description}

produces:

Still spaced

Best Answer

Perhaps there is better method, but it seems that if you eliminate the \\ and include a \vspace{-\baselineskip} before the verbatim environment you get reasonable looking results:

enter image description here

\documentclass{article}
\newcommand*{\var}[1]{\texttt{#1}}%  Macro definition not provided in MWE

\begin{document}
\subsubsection{User Default Page URL}

\begin{description}
\item[Rationale] \hfill 

This is the default page displayed to a user when
(s)he opens a new window or tab in Microsoft's Internet Explorer browser.
\item[Data Sources] \hfill\vspace{-\baselineskip}

\begin{verbatim}
[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer]
"Default_Page_URL"="${url}"
\end{verbatim}
\item[Log Format] \hfill \vspace{-\baselineskip}
%
\begin{verbatim} 
uDefaultPageUrl=${url}
\end{verbatim}
\item[Description] \hfill 

The variable \var{url} is escaped using the URL
escaping scheme defined in \ref{urlescape}.
\end{description}
\end{document}
