# Is it possible to get the leading spaces in copy/paste from PDF?

Using this solution Only Select Code without Line Numbers I allow the listings to be copyable from PDF w/o the line numbers and many extra spaces.

But that also removes the leading spaces used for indentation!

\documentclass[11pt,letterpaper]{memoir}
\usepackage{listings}
\usepackage{accsupp}

\lstset{
frameround=fttt
,language=SQL
,numbers=left
,breaklines=true
,showstringspaces=false
,basicstyle=\small
,numberstyle=\noncopynumber
,columns=flexible
}

\newcommand{\noncopynumber}[1]{
\BeginAccSupp{method=escape,ActualText={}}
#1
\EndAccSupp{}
}

\begin{document}
\begin{lstlisting}
declare @a int

if @a = null
select 'null' as outcome
else
select 'not null' as outcome
\end{lstlisting}
\end{document}


This is what I get when pasting code from PDF:

declare @a int
if @a = null
select ' null ' as outcome
else
select 'not null ' as outcome
if null = null
select 'equal' as outcome
else
select 'not equal' as outcome


There are extra spaces around null on line #3 and one on line #5 but all leading spaces are gone.
