Can be fixed in lexer.py:200 by changing the regex from r'^\s*' to r'^[ \t\v]*'. This makes the whitespace list limited, but that should not be an issue without re.UNICODE or re.LOCALE

Hmm. There still needs to be a way of including blank lines in the code which do not get rendered in the output, but are only there for legibility. I propose that lines containing line_statement_prefix (or line_comment_prefix) and nothing else be the mechanism for this. Currently they are not handled in a helpful way (filed as #204 and #205).

Just discovered that {##} is a tolerable workaround.

Newlines after a end control bloc (endif, endfor) are still eaten up:

%% for i in range(2)
hello
%% endfor

I want to be alone

renders as =>

hello
hello
I want to be alone

Is this expected behavior? This doesn't make sense to me regarding the documentation.

This has been resolved a long time ago, but I'm not sure why. I still see my newlines eaten up with line statements on version 2.10.3...

Any way of getting this to work?
