Author: jilles Date: Mon Dec 29 15:33:20 2014 New Revision: 276365 URL: https://svnweb.freebsd.org/changeset/base/276365 Log: MFC r276037: sh: Remove EXP_REDIR. EXP_REDIR was supposed to generate pathnames in redirection if exactly one file matches, as permitted but not required by POSIX in interactive mode. It is unlikely this will be implemented. No functional change is intended.
