Small code fixups

> Enabled -Wall -Wextra -Wpedantic to catch errors
    - Silenced resulting "unused parameters" warnings
    - Fixed char omission in protected Fl_Terminal::insert_char() methods
> Self doc code and better comments in RingBuffer::resize()
> Changed private RingBuffer::clear_disp_row() -> clear_disp_rows()
> Added private RingBuffer::hist_rows()/disp_rows() setter methods
> Added private RingBuffer::offset_adjust() method for adjusting RingBuffer offset_
> Fixed comment typos
> Remove white space inside outer parens of while()/if()/etc
