I found a small incompatibility between bash 1.12 and /bin/sh
SunOS 4.1.2.  I'm not sure if this is a bug, or `implementation
defined' incompatibility.

The following code shows that bash's `case' thinks a string
`abcd' matches *<newline>* while /bin/sh does not.

-- >8 -- 
shadow 100) bash -c 'echo $BASH_VERSION'
1.12.1
shadow 101) cat case.sh
NL='
'

for i in "$@"
do
	case $i in
	*$NL*) echo "case: $i: newline detected"
	esac
done
shadow 102) /bin/sh case.sh abcd 'ab
> cd'
case: ab
cd: newline detected
shadow 103) bash case.sh abcd 'ab
> cd'
case: abcd: newline detected
case: ab
cd: newline detected
shadow 104)
