commit 8bc2fe488957946d2cdccda3ce8d4f39e4003ea0
Author: Pedro Alves <palves@redhat.com>
Date:   Wed Mar 12 20:32:53 2014 +0000

    Factor out foreground/background execution command preparation.
    
    All execution commands currently have this pattern:
    
      /* If we must run in the background, but the target can't do it,
         error out.  */
      if (async_exec && !target_can_async_p ())
        error (_("Asynchronous execution not supported on this target."));
    
      /* If we are not asked to run in the bg, then prepare to run in the
         foreground, synchronously.  */
      if (!async_exec && target_can_async_p ())
        {
          /* Simulate synchronous execution.  */
          async_disable_stdin ();
        }
    
    This patch factors that into a shared function.
    
    attach_command installs a cleanup to re-enable stdin, but that's not
    necessary, as per the comment in prepare_execution_command.  In any
    case, if someday it turns out necessary, we have a single place to
    install it now.
    
    Tested on x86_64 Fedora 17, sync and async modes.

    	* infcmd.c (prepare_execution_command): New function, factored out
    	from several execution commands.
    	(run_command_1, continue_command, step_1, jump_command)
    	(signal_command, until_command, advance_command, finish_command)
    	(attach_command): Use prepare_execution_command.
