New message, add BCC recipient, Ctrl+Shift+Enter.
Check message in Outbox. No To: undisclosed-recipients: ;

Works when message is sent straight away.
This addes the undisclosed-recipients when the message is saved in the Outbox. However, it cannot be sent, I get:

There are non-ASCII characters in the local part of the recipient address . This is not yet supported. Please change this address and try again.

Note the space before the dot, so the %s replacement has actually not worked :-(

errorIllegalLocalPart=There are non-ASCII characters in the local part of the recipient address %s. This is not yet supported. Please change this address and try again.
This is really messy. When I add undisclosed-recipients with the patch, sending fails here:

I only get one empty address :-( - Hence the replacement of % with an empty string. Without the patch, I get the BCC recipient. So something really twisted going on. So if some other code sees the To: it doesn't collect the BCC or some such :-(
OK, this fixes it. Note that there was a bug in StripOutGroupNames(). With the correction the debug shows:
=== send buf |undisclosed-recipients: ;,jorgk@jorgk.com|
=== send buf | ,jorgk@jorgk.com|

Without the correction it shows:
=== send buf |undisclosed-recipients: ;,jorgk@jorgk.com|
=== send buf |u ,jorgk@jorgk.com|

so the group isn't correctly stripped. "u" doesn't have an e-mail address, hence the error described in comment #1.

I left the debug in for the reviewers convenience.

This fix comes too late for my Christmas message which sadly went out without
To: undisclosed-recipients: ;

Thanks, I have tested both Send and Send later with a Bcc recipient, and they work with this patch.
