In La@TeX{} input, @samp{\begin} and @samp{\end} tags must balance.
You can use @kbd{C-c C-e} (@code{tex-close-latex-block}) to insert an
@samp{\end} tag which matches the last unmatched @samp{\begin}. It
also indents the @samp{\end} to match the corresponding @samp{\begin},
and inserts a newline after the @samp{\end} tag if point is at the
