This is not true, except in some older versions of sh. Current
versions of sh do not do it; I don't think ksh ever did. Posix.2
specifies that only a path search is performed. The current directory
is not searched unless it is in $PATH ``to avoid introducing
suceptibility to trojan horses that a user might be trying to avoid by
leaving `.' out of $PATH.''
