Handling long messages inserts an extra space

[realies]

When using bitlbee-facebook with the option to concatenate long messages when they're received between a certain time interval, bitlbee-facebook concatenates the messages by inserting an additional space character after each concatenated message. This, for example, breaks long URLs. Would it possible to concatenate without a space between messages?

That's not bitlbee-facebook, that's bitlbee's paste_buffer, closing because this doesn't belong here.

Also, it's not a space, it's a newline, because the feature is about sending multiple lines as a single message. Not sure what to do there.
