commit dbdb26547c769f1f9e64cc2479cb9eeef1e5ac6a

    Fix \e[K if current column is beyond terminal width
    
    In ordinary terminals, current column is never bigger than terminal width, 
but
    in coterm, we intentionally allow it in order to leave line wrapping up to
    Emacs. See the commentary at the start of ';;; Terminal emulation' section 
in
    coterm.el for more information.
