[RCD] Roundcube breaks GPG

Noticing a strange phenomenon with the latest SVN of RC, when you send a GPG-encoded message from RC it gets corrupted. It looks like each line of the coding is "double spaced"-- extra linefeeds get inserted. I've never had this happen with any other email/webmail clients.

I'd like to submit a patch to allow GPG to work as it's quite useful, but I've been going over the code and I can't find why this is happening--I'm assuming it's something in sendmail.inc, I just can't put my finger on it. Can anybody offer any assistance?

Thanks, Ben
