Fix matching multiline control lines in templates with CRLF line endings
Fixed issue where control statements on multi lines with a backslash would
not parse correctly if the template itself contained CR/LF pairs as on
Windows. Pull request courtesy Charles Pigott.
A missing '\\' meant that it would actually allow
```
% if foo \r
bar:
```
in a template file and not match if the file actually had a `\r` char
