119	# Notes:
120	# - MakeParserForCommandSub() instantiates a new WordParser, so we can safetly
121	# change state in the top-level one only
122	# - BoolParser is called for [[ ]] and uses the same self.w_parser. I think
123	# that's OK?
124
125	# So I think we can change state in WordParser. (Also possible in
126	# CommandParser but meh).
127	#
128	# self.is_multiline = False
129	#
130	# When this is flag is on, then we
131	#
132	# Id.Op_Newline -> Id.WS_Space or Id.Ignored_LineCont
133	# - and then that is NOT passed to the command parser?
134	# - Or you can make it Id.Ignored_Newline
135	#
136	# BUT if you get 2 of them in a row without a comment, you can change it to:
137	# - Id.Op_Newline?
138	#
139	# Actually this is very simple rule and maybe can be done without much
140	# disturbance to the code.
141	#
142	# cursor_was_newline might need more state?
