Tim,
I cannot find a way to continue adding comments to the [bugs:#1696] after your request for MWE, so here it is (in case SF strips the leading spaces too, the first group of 3 lines has 1, 2 and 3 leading tabs and the 2nd group has 2, 4 and 6 leading spaces):
\begin{lstlisting}
aaaaaaaaaaaa
bbbbbbbbbbbbb
ccccccccccccccccc
aaaaaaa
bbbbbbbbb
ccccccccccccc
\end{lstlisting}
If you tried to create {lstlisting} environment, then paste the contents between \begin and \end into the editor, they would be stripped of the leading spaces and tabs.
By the way, this is not a new issue in 2.10.8, it existed in 2.8 as well if it matters.
Thank you!
I think sourceforge requires you to be logged in to add comments to an existing request.
The behavior is actually intended if you have
Options -> Editor -> Indentation Mode
set to "Indent and unindent automatically". Choose one of the other options to prevent this behavior.Diff:
