Sorry if I was unclear but it is the  "." command that causes the
error. If you add "return 0" at the end of sdf2, you will see no
trace.
I would probably consider it a bug if "." was returning 1 without
triggering an error.

Now you could consider a bug to get the "[[ $# -ge 2 ]]" instead of
"." in BASH_COMMAND, though I guess some people might, on the
contrary, find it useful.
