Insert some URL, e.g. "http://www.gnu.org".
Move point inside the URL.
M-x load-library RET ffap RET
M-x ffap-other-window RET RET
The URL is now opened in the default browser, as expected.  However, the
window is also split, even if the default browser is external (not
EWW).  ffap-other-window should not change the window configuration
unless it has to display a buffer.

Subject: [PATCH] ffap: Don't switch window unless needed

When using ffap-other-window, don't change the window configuration
unless a new buffer has actually been created (Bug#25352).

* lisp/ffap.el (ffap-other-frame): Don't change the window
configuration if no new buffer has been created.
* test/lisp/ffap-tests.el (ffap-other-window--bug-25352): Add unit
test.
