We want to do that each time the user jumps a line, just after the new line
is inserted. So the hook would be:
------------------------------------------------------
--------------------------------------------------------
:hook InsertChar \n %{ exec k<a-x> s^\h+<ret>y j<a-h>P }
------------------------------------------------------
--------------------------------------------------------
(exec concatenates the keys for all argument, so the spaces will be ignored,
allowing for clearer separation. either use <space> or quote the argument to
use a space key)
That works, however if the phase *2.* raises an error, the +:exec+ will stop
and the user will get it's selections on the previous line. the solution
is to use a *draft* context, instead of the one the user is interacting with.

:hook InsertChar \n %{ exec -draft k<a-x> s^\h+<ret>y j<a-h>P }

That way, exec is executed in a *copy* of the user's context, which means it
manipulates a *copy* of the user's selections.
