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.
