When an Fl_Text_Editor's buffer()->remove() is called,
the text insert cursor disappears. (ie. *not* the mouse cursor)
Attaching cursor_problem.cxx that shows the problem:
1) Run the program, text appears with cursor at top
2) Hit 'remove(5,6)' button that removes the text at position [5]
3) Cursor disappears
Problem is in (3), cursor should remain.
It seems no matter where the cursor is, remove() causes it to disappear.
Either this is a bug, or should be documented behavior.
