	Hi Denis,

``RATIONALE

     Some older implementations searched the current directory for the
file, even if the value of PATH disallowed it. This behavior was omitted
from this volume of IEEE Std 1003.1-2001 due to concerns about introducing
the susceptibility to trojan horses that the user might be trying to avoid
by leaving dot out of PATH.'' --The Open Group Base Specifications Issue 6

	You have to append a `current' dot to your $PATH environment,
~ $ PATH="$PATH:." && echo $PATH && . test.sh
/sbin:/usr/sbin:/bin:/usr/bin:.
local
