vis-lockfiles/init.lua, branch improve_abort

restore the previous file on abort

2024-05-10T06:46:51+00:00

This feature requires a vis build supporting changing a window's
file from Lua.
To enable it set the module's change_file_on_abort member to true.

stop further WIN_OPEN event handling if we aborted

2024-05-04T09:40:50+00:00

Closing the window invalidates the handle passed to further
event handlers probably causing them to crash.

remove obsolete event handling code

init.lua: no need to defer to handler apparently

init.lua: working version

2024-05-04T09:31:16+00:00

initial draft supporting autoclose and abort

2024-05-04T09:31:16+00:00

Currently this breaks with my config which sets window options
during WIN_OPEN events which causes a UI_DRAW event closing the window
during its WIN_OPEN event.
