Fix treatment of whitespace after a backslash on MS-Windows.

 job.c (construct_command_argv_internal): Don't treat a backslash as an
 escape character before whitespace, if the shell is not a Posix
 shell.   For the description of the problem, see
 http://lists.gnu.org/archive/html/make-w32/2013-04/msg00014.html.
