+There is no explicit option to turn off alignment; it is implicitly
+disabled if one of --separator or --nameprefixes option is used.
+
+--separator was added in 2007, --nameprefixes - in 2009. So let's use
+--separator to extend range of versions we are compatible with. Note that
+one or another must be used, current parsing is broken otherwise.
