>Description:
/bin/sh does not parse the case construct according to SUSv3.
XCU describes it as:
 case word in
     [(]pattern1)                 compound-list;;
     [(]pattern2|pattern3)        compound-list;;
     ...
 esac

when sh(1) meets a leading parenthesis, it errors out with
Syntax error: word unexpected (expecting ")")

ksh(1) handles it correctly.
>How-To-Repeat:
Run the following shell script:

#!/bin/sh
case foo in
	(foo|bar)
		echo found;;
	*)
		echo not found;;
esac
