rosbash: "find: paths must precede expression" on auto-complete attempt of rosmsg (with msg files in the CWD)

[gavanderhoorn]

To reproduce:

docker run -it --rm ros:melodic
source /opt/ros/melodic/setup.bash
roscd sensor_msgs/msg
rosmsg show sen<tab>

error returned then is:

find: paths must precede expression: `CameraInfo.msg'
find: possible unquoted pattern after predicate `-name'?

I've tried to understand what is going on in the auto-complete hook for rosmsg, but I've never had the pleasure of working with compgen so it's all black magic to me. It seems like the problem could be somewhere around:

ros/tools/rosbash/rosbash

Lines 902 to 905 in fd86014

	show|info|users|md5)
	opts=$(_msg_opts ${COMP_WORDS[$COMP_CWORD]})
	COMPREPLY=($(compgen -W "$opts" -- ${arg}))
	;;

I have a hunch that something like this is happening.

@gavanderhoorn Yes, that was the actual issue. #218 provides a fix.
