From b520d20b8122a783f99f088758b78d928f70ee34 Mon Sep 17 00:00:00 2001

Subject: [PROPOSED] Fix Makefile quoting bug

Problem with INSTALLARGS reported by Zefram in:
https://mm.icann.org/pipermail/tz/2017-October/025360.html
Fix similar problems too.
* Makefile (ZIC_INSTALL, VALIDATE_ENV, CC, install)
(INSTALL, version, INSTALLARGS, right_posix, posix_right)
(check_public): Use apostrophes to prevent undesirable
interpretation of names by the shell.  We still do not support
directory names containing apostrophes or newlines, but this is
good enough.
* NEWS: Mention this.
