Dict protocol changes string

Hi,

I use pass and userdb with dict protocol in a similar way:

key passdb { key = passdb^MAuth-User: %u^MAuth-Pass: %w^MAuth-Protocol: %s^MClient-IP: %r format = json }

(^M is an \r character, inserted with vi CTRL-v + enter)

Until 2.2.24 this has worked, but 2.2.25 seems to convert that ASCII 13 into an ASCII 1 and an "r".

Python printout from what I get with 2.2.25:

'Lshared/passdb\x01rAuth-User: user\x01rAuth-Pass: pass\x01rAuth-Protocol: pop3\x01rClient-IP: 1.2.3.4'

Is this change intentional? Why?
