Re: backspace mode and control-u
first, in insert mode, control-u seems to do nothing. is there a setting to allow this?
second, is there an equivalent to vim's :set backspace=indent ?
id even be happy with :set backspace=
right now it seems default to :set backspace=start,indent,eol
what control-U does changes based on the :set backspace setting
i normally run with :set backspace=indent, and control-u will delete to start of line, or start of insert mode, whichever is closer.
