tramp (2.1.18-23.2); Dont work with stat from coreutils-8.6

[Terechkov Evgenii]

Hi, all.

Seems like I hitted bug in tramp that make it broken on my system since
I upgrade from coreutils-8.5 to coreutils-8.6. Here is problem
description:

1) When I tried to open "/sudo::/etc/net/ifaces" directory, I get
following traceback:

Debugger entered--Lisp error: (wrong-type-argument numberp 
1287212125\.000000000\.0)
  floor(1287212125\.000000000\.0 65536)
  tramp-convert-file-attributes(["sudo" "root" "evg.krastel.ru" 
"/etc/net/ifaces/"] (("`/etc/net/ifaces/'") 17 0 0 1287212125\.000000000\.0 
1285249174\.000000000\.0 1285249174\.000000000\.0 4096.0 "drwxr-xr-x" t 
557742.0 -1))
  tramp-handle-file-attributes("/sudo:address@hidden:/etc/net/ifaces/")
  ...

2) I traced problem down to function tramp-do-file-attributes-with-stat
and noticed that this function adds some ".0" to stat's output. Here is
checks I made with old and new versions of coreutils:

====8<==with coreutils-8.5======================================================
 $stat -c '%X %Y' /etc/net/ifaces
1287212125 1285249174
================================================================================

====8<==with coreutils-8.6======================================================
$stat -c '%X %Y' /etc/net/ifaces 
1287212125.000000000 1285249174.000000000
================================================================================

3) Here is notes about this change in behavior from NEWS file of
coreutils-8.6:

====8<==NEWS.bz2================================================================
  stat now outputs the full sub-second resolution for the atime,
  mtime, and ctime values since the Epoch, when using the %X, %Y, and
  %Z directives of the --format option.  This matches the fact that
  %x, %y, and %z were already doing so for the human-readable variant.
================================================================================

4) So I wrote this little patch to tramp.el:

-    "((%s %s || %s -h %s) && %s -c '((\"%%N\") %%h %s %s %%X.0 %%Y.0 %%Z.0 
%%s.0 \"%%A\" t %%i.0 -1)' %s || echo nil)"
+    "((%s %s || %s -h %s) && %s -c '((\"%%N\") %%h %s %s %%X %%Y %%Z %%s.0 
\"%%A\" t %%i.0 -1)' %s || echo nil)"

It works for me, but probably it is not right fix for this case. I hope
somebody of tramp's developers will do it right :-)
