/** Handles a keystroke.
This \p protected method handles a keystroke in an Fl_Input or derived
class. It handles compose key sequences and can also be used e.g. in
Fl_Multiline_Input, Fl_Float_Input and several more derived classes.
The details are way too complicated to be documented here and can be
changed as required. If in doubt, please consult the source code.
\returns 1 if the keystroke is handled by us, 0 if not.
