This change was necessary to add a new "editenv" command. This change allows the readline() function to edit a string instead of just enter one from scratch. In theory this feature could be used for other areas of U-Boot in the future, but at this point the only user of it would be the "editenv" command which I submitted a patch for. If the 'editenv' patch is rejected, I don't mind this one being rejected too.
