Wait.  This is fine, but, as the comments indicate, the code was taken
from the function command_line_input in top.c, which has the same bug:

      p1 = rl;
      /* Copy line.  Don't copy null at end.  (Leaves line alone
         if this was just a newline)  */
      while (*p1)
	*p++ = *p1++;

      xfree (rl);		/* Allocated in readline.  */

      if (p == linebuffer || *(p - 1) != '\\')
	break;


Jason, can you sneak in a fix for that too?

Thanks
Elena
