Requiring trailing whitespace for block quotes seems problematic

[willfaught]

For example (space at the end of the second line):

> First paragraph.
> 
> Second paragraph.

Won't trailing whitespace be highlighted and flagged as a mistake in a lot of editors?

I get wanting it to be consistent with other syntax that has a space after the symbol in the first column, like headers or lists, but perhaps it's worth making an exception in this case?

Trailing whitespace isn't required. You can have a newline directly after the >.

Thanks for the correction!
