Why rosnode does not allow l as list like rosservice and rostopic?

https://github.com/ros/ros_comm/blob/indigo-devel/tools/rosnode/src/rosnode/__init__.py#L790

rostopic and rosservice allows l like::

• https://github.com/ros/ros_comm/blob/indigo-devel/tools/rosservice/src/rosservice/__init__.py#L735
• https://github.com/ros/ros_comm/blob/indigo-devel/tools/rostopic/src/rostopic/__init__.py#L1770

Are there some reasons rosnode does not allow l as list?

This is actually a bug in rosservice and rostopic. The following check:

if command in 'list':

is wrong since when you call rostopic i it will actually invoke list instead of info (because it is checked first).

Also neither any of the other commands have that shortcut not any of the other tools (rosconsole, rosmsg, rosparam). Therefore the right way to address this will be to fix the comparion in rosservice and rostopic to compare the whole command string.
