* Fix escape_except_blockquotes for greater than 9 block quotes in 1 string

When there are more than 9 block quotes in a string `escape_except_blockquotes` will fail do to the fact that the `BLOCKQUOTE_TOKEN_{i}` replacement will incorrectly match for both `BLOCKQUOTE_TOKEN_1` and `BLOCKQUOTE_TOKEN_10`

This just extends it to `BLOCKQUOTE_TOKEN_{i}_END` so this accidental match doesn't happen.
