+/* This is like readline(), but it has some gdb-specific behavior.
+ gdb can use readline in both the synchronous and async modes during
+ a single gdb invocation. At the ordinary top-level prompt we might
+ be using the async readline. That means we can't use
+ rl_pre_input_hook, since it doesn't work properly in async mode.
+ However, for a secondary prompt (" >", such as occurs during a
+ `define'), gdb just calls readline() directly, running it in
+ synchronous mode. So for operate-and-get-next to work in this
+ situation, we have to switch the hooks around. That is what
