It's because the gtk scrollbar isn't flexible enough to cope with all
the possibilities allowed by emacs' text display.

The main issue, AIUI, is that the gtk scrollbar mechansim _assumes_ that
"end of buffer" is always at the bottom of the window (except when
that's impossible, such as a document smaller than the window), but
emacs allows the end-of-buffer point to be positioned anywhere in the
window.  So to allow users full flexibility in positioning, emacs
defines a sort of "overshoot" area past the end of the document.
