commit ac8beb00975688cc049035a6d347734bd6416d8a
Author: Eric Blake <address@hidden>

    INSTALL: convert to '' quoting, drop blank line at end
    
    This is allowed by recent GNU Coding Standards changes, and
    mirrors recent gnulib changes:
    https://lists.gnu.org/archive/html/bug-gnulib/2012-01/msg00267.html
    https://lists.gnu.org/archive/html/bug-gnulib/2012-01/msg00298.html
    
    I've confirmed that after these changes, the INSTALL generated and
    installed by autoconf matches the INSTALL.ISO in gnulib.
    
    * Makefile.am ($(srcdir)/INSTALL): Match gnulib INSTALL.ISO.
