In a string or comment, kill either to the end of sentence (as
`kill-sentence') or to the end of the string or comment,
whichever is nearer.  Do not kill a closing string or comment
delimiter.  Treat ARG in the same way as `kill-sentence'.

Outside of strings and comments, this should generally behave as
`kill-sentence', but no guarantees are made."
