I have here two interrelated whitespace formatting fixes for libxc:

 1/2 libxc: Remove hard tabs which ought to be 4 spaces
 2/2 libxc: Remove "tab-width: 8" from emacs local variables

There is no functional change, as is easily verifiable.

I would like to propose these for a freeze exception for Xen 4.4, on
the basis that it will make it marginally easier to port future
patches to 4.4 if we don't have to deal with whitespace conflicts.

Some of the files in libxc have hard tabs.  Many (but not all) of
libxc's files have an emacs local variable section declaring tab-width
to be 4.

Of the files which have both of these properties, some of the tabs are
supposed to stand for 4 spaces and some of them 8.

Replace the ones where they are supposed to stand for 4 spaces with
actual spaces.  After this patch the only hard tabs in libxc are ones
which expect to expand to 8 spaces.  This will allow us to remove the
tab-width settings.

I'm not fixing the 8-space tabs to avoid needless whitespace churn.

It's it a bit late for that after this patch? Given there is already
pain here I'd rather just rip the plaster off all at once...

  To: xen-devel; +Cc: George Dunlap, Ian Jackson, Ian Campbell, Stefano Stabellini

Tabs must universally expand to 8 spaces.  All the (remaining) hard
tabs in libxc expect this.  Attempting to define an alternative
setting is simply wrong because not all tools (or indeed all emacsen)
will respect it.

FYI I used the script below to add some missing CCs to this and my
other series.

#!/usr/bin/perl -w
#
# usage
#   git-filter-branch --msg-filter \
#        ".../auto-cc-maintainers `pwd`/xen.git xen-devel@lists.xen.org"
#
# (args are things never to add to CCs)

use strict;
use IO::File;

die unless @ARGV;
die if $ARGV[0] =~ m/^-/;

our %got;

my $xendir = shift @ARGV;
chdir $xendir or die "$xendir: $!";

$got{lc $_}++ foreach @ARGV;

while (<STDIN>) {
    print or die $!;
    $got{lc $1}++ if m/^[-0-9a-z]+: (.*)$/i;
}        

my $anyyet=0;

open CCS, "git-show $ENV{GIT_COMMIT} | scripts/get_maintainer.pl |" or die $!;
while (<CCS>) {
    chomp;
    next if $got{lc $_};
    print STDERR "\n" if !$anyyet++;
    print STDERR "$ENV{GIT_COMMIT} ADDING $_\n";
    print "CC: $_\n" or die $!;
}
$!=0; $?=0; close CCS or die "$? $!";
