I hit C-' by mistake inbetween an isearch while in an org file and that
called `org-cycle-agenda-files` and switched to a different org file while
the search was active.

I tried doing
- C-s
- search something that fails search / search something that has search hits
- C-' (switch to a different org file)
- C-g

But that issue did not occur this time; isearch quit gracefully.

Doing ag showed me that the ido-ubiquitous.el is advising that:

(defadvice call-interactively (around ido-ubiquitous activate)
  "Implements the behavior specified in `ido-ubiquitous-command-overrides'."
  (let* ((cmd (ad-get-arg 0))
         (override (ido-ubiquitous-get-command-override cmd)))
    (when override
      (ido-ubiquitous--debug-message "Using override `%s' for command `%s'"
                                     override cmd))
    (ido-ubiquitous-with-override override
        ad-do-it)))

I don't understand what it's doing in this advice though.
