[Emacs-diffs] emacs-25 6475f92: Port "$@" to OpenIndiana ksh93

[Paul Eggert]

branch: emacs-25
commit 6475f9265ecf21a8d49bc3ac0dc66010c9ec6b05
Author: Paul Eggert <address@hidden>
Commit: Paul Eggert <address@hidden>

    Port "$@" to OpenIndiana ksh93
    
    In http://lists.gnu.org/archive/html/bug-autoconf/2015-12/msg00000.html
    Pavel Raiskup reports that ${1+"$@"} runs afoul of a bug in /bin/sh
    (derived from ksh 93t+ 2010-03-05).  ${1+"$@"} works around an ancient
    bug in long-dead shells, so remove the workaround.
    * admin/check-doc-strings, configure.ac, lib-src/rcs2log:
    Use plain "$@" rather than ${1+"$@"}.
