[issue28945] get_boundary invokes unquote twice

[Eric Lafontaine]

Eric Lafontaine added the comment:

Hi,

I would like to have a bigger set of user testing this patch before it gets approve... I really don't know all the extent to which it's a good/bad idea.  

The proposition was to not do the unquote in the rfc2231 collapse method.  It doesn't break anything on my machine on all the email tests... but I can't feel safe.

I also added the 2 test case for future support (multiline boundary and single line boundary).  It's basically the code I pasted on my answer on the 2016-12-20.

Let me know what you think.  Is it there we should stop doing it?

Regards,
Eric Lafontaine
