I fixed that.

I also removed the following entry from the NEWS file.  It doesn't
make sense to me to write that the fltk backend is new, and that it
"now implements some features".  Which features should be listed?  All
the features of the fltk backend are new since the fltk backend itself
is new...

    The fltk graphics backend now implements the following callback
    properties: keypressfcn, keyreleasefcn, windowbuttondownfcn,
    windowbuttonmotionfcn, windowbuttonupfcn, and currentpoint.  These
    enable keyboard and mouse interaction, an example of which can be
    seen in the __fltk_ginput__.m script.

I think that we should fix that bug before 3.4 is released.  I've
already filed a bug report about it.  Maybe I should tag it as a
blocker in the bug tracker?
