I have a patch that implements the best part of iswitchb functionality
without changing the default minibuffer user interface. It provides
the following benefits:
1. After typing C-x b: each M-n (or down-arrow) key will put the
next buffer name to the minibuffer, starting with the most recent
buffer and going in the order buffers are stored in the buffer list.
2. After typing C-x b: C-s or C-M-s will incrementally search the
buffer list for the buffer name that matches the search string or
regexp. So to switch to the buffer, the users can simply type any
unique part of the buffer name or to repeatedly type C-s until seeing
the needed buffer name, e.g.: `C-x b C-s [substring] C-s ... RET'
This is implemented by putting the buffer list to the list of default
values of the minibuffer created by the `interactive' code character `B':
