ginput has a way to do it. From docs:
If n is zero or negative, accumulate clicks until a middle click
(or potentially both mouse buttons at once) terminates the
input.
http://matplotlib.sourceforge.net/api/pyplot_api.html#matplotlib.pyplot.ginput
Pressing [enter] also terminates the points acquisition.
