>Description:
Kernel doesn't seem to be invoking script itnerpreters, but rather allowing interpretation by the current shell.

I've reproduced this on both 6.3-STABLE and 6.2-RELEASE-p8 where I originally noticed the issue. I checked /usr/src/UPDATING, but found no reference. I've also looked through previous PRs unsuccessfully identifying a similar bug report.

>How-To-Repeat:
test# cat test.sh
#!/bin/sh

echo SHELL $SHELL
test# ./test.sh
SHELL /bin/csh
test# sh
# echo $SHELL
/bin/csh
# exit
test# bash
[root at test ~]# echo $SHELL
/bin/csh
