Problem with path encoding of slashes and purl 1.2

[duarnad]

Hi,
First thanks for this very useful library.
We just met a problem due to purl upgrading from 1.1 to 1.2.
We have some scenarios with post requests like this one (including slashes) :
And I make a POST request to "users/{{ENCODED_EMAIL}}/contents/{{CONTENT_B64URL_ENCODED}}"
It was working but we recently see that the slashes were replace by %2f.
This is a new feature of purl 1.2 which manages slashes in path_segment.
With purl 1.1 the behavior is like this :

>> u = purl.URL().scheme('http').domain('www.example.com').path('/some/path').query_param('q', 'search term') 
>>> new_url = u.add_path_segment('here/there')
>>> str(new_url)
'http://www.example.com/some/path/here/there?q=search+term'

With purl 1.2 the behavior is like this :

>>> u = purl.URL().scheme('http').domain('www.example.com').path('/some/path').query_param('q', 'search term')
>>> new_url = u.add_path_segment('here/there')
>>> str(new_url)
'http://www.example.com/some/path/here%2Fthere?q=search+term'
