I will keep this opened for feedback.

• add: when editing too long lines (2000+ chars), editor turns lexer off for a few seconds. That is to prevent caret rendering glitches on editing very long lines. New option for this: "max_line_len_for_editing_keeping_lexer".

@veksha , you can test it from source. it was added from your feedback when you said about 'editing of NN kb lines is giving rendrering delays'.
