Crash on pasting text.

The report was this:

I can reproduce it by restarting DreamPie and pasting it again. Since github is trying to parse the html I pasted the failing text on my site:

http://welbornprod.com/paste/?id=gezx

It's not code that goes into any of my programs, just a small test I was running with lxml.html.

I know what caused it. I had embedded python code inside of that string, with docstrings in it.

So.. this made it crash:
txt = """ <-html stuff-> """ python stuff """ <-more html stuff-> """

The fix was to do this:

txt = ''' <-html stuff-> """ python stuff """ <- more html stuff -> '''

(just changed the triple-quote style)

Oddly, I discovered it by reverting back to IDLE, where I got SyntaxError: invalid syntax. When I saw that I immediately realized what had happened.
