+ This file is used by exec_file_command, to do the work of opening
+ and processing the exec file after any prompting has happened.
+
+ And, it is used by child_attach, when the attach command was
+ given a pid but not a exec pathname, and the attach command could
+ figure out the pathname from the pid. (In this case, we shouldn't
+ ask the user whether the current target should be shut down --
+ we're supplying the exec pathname late for good reason.) */
