restore the current line, so the editing operations can actually modify the input buffer, instead of the history string.

and a bit of foreshadowing... :)

load_previous_page calls directly do_load_url, where the proxy reset happens in load_url.

after the re-exec diff, the configuration gets loaded *before* and then the proxy list is initialized. Thus once we start the UI the proxy list is always empty. Solve the headaches by using TAILQ_HEAD_INITIALIZER. Or, in theory we could also avoid the initialization at all, since globals vars should be zeroed.

there's a close relationship between the echoarea and the minibuffer, but let's call it echoarea for now.
