My response:

This is currently configured in the code. Specifically roundupdb.py in
send_message. Search for X-Roundup. This would be good to add
upstream. I am actually surprised it's not there already.

However I suggest X-Roundup-issue-id rather than number. The field
that holds the number is id, so this makes sure that the header name
won't collide with a new "number" field.
