Author: jilles Date: Sun Dec 9 19:14:21 2018 New Revision: 341767 URL: https://svnweb.freebsd.org/changeset/base/341767 Log: MFC r341164: sh: Fix ${param?} default error message If word in ${param?word} is missing, the shell shall write a default error message. So expanding ${param?} when param is not set should write an error message like sh: param: parameter not set This was broken by r316417.
