Deletes a sequence of characters from the buffer. @n_chars characters are
deleted starting at @position. If @n_chars is negative, then all characters
until the end of the text are deleted.
If @position or @n_chars are out of bounds, then they are coerced to sane
values.
Note that the positions are specified in characters, not bytes.
