Blockquote. There are many times I would like to do a blockquote and have to either "quote" the quote, italicize the quote, or use

  preformatted quotes.

Each of the alternatives has drawbacks.

I would humbly request pg to add the email convention "> " at the beginning of a line to format as a block quote.

> This would be a block quote. It goes on as long as the paragraph goes on. Note that each line does not start with "> " - that would be unnecessary since that is already done with the preformatted syntax.

This would no longer be block quoted.
