The message is misleading, but the warning is warranted.

A leading, trailing, or double colon in $PATH is equivalent to having a
dot there.  And root user's should _never_ have a dot in their path since
you never know if a user is going to put a trojan "ls" somewhere where you
will inadvertantly run it.
