fix handling of multiple Content-type headers
This can happen if an error happens while sending
application/mercurial-0.1 content. The error page will
be sent resulting (for at least lighttpd) in the following
headers:
Content-type: application/mercurial-0.1
Content-type: text/html
which result in req.proto = 'application/mercurial-0.1, text/html'
fix issue344
200 Script output follows
content-type: text/plain
content-length: 157
content-disposition: filename=sometext.txt
This is just some random text
that will go inside the file and take a few lines.
It is very boring to read, but computers don't
care about things like that.
