*: make GNU licensing statement forms more regular
...
This change retains "or later" state! No licensing _changes_ here,
only form is adjusted (article, space between "GPL" and "v2" and so on).

line editing: add an option to emit ESC [ 6 n and use results
...
This makes line editing able to recognize case when
cursor was not at the beginning of the line. It may also
be adapted later to find out display size (serial line users
would love it).
