======================================================================
Major changes between "less" versions 409 and 415
* New --follow-name option makes F command follow the name of a file
rather than the file descriptor if an open file is renamed.
* Make searching with -i/-I work correctly with non-ASCII text.
* Fix DJGPP build.
======================================================================
Major changes between "less" versions 406 and 409
* Support CSI escape sequences, like SGR escape sequences.

deinitialization string does something unnecessary, like clear-

--no-keypad
Disables sending the keypad initialization and deinitialization

strings make the numeric keypad behave in an undesirable manner.
-yn or --max-forw-scroll=n
Specifies a maximum number of lines to scroll forward. If it is
necessary to scroll forward more than n lines, the screen is
repainted instead. The -c or -C option may be used to repaint
