When I reply to a message (original message is either plain text or HTML) in plain text mode, the whole quoted body appears in on line without any line breaks. I have the problem today on Mac but not on Windows.
I don't think this is really a PP bug. At least, I see the problem on Windows as well. It turns out that plaintext quoting is completely screwed up in lots of ways: 1. someone broke the plaintext quotation code in the editor 2. someone else disabled it so that plaintext quotations get put in as html blockquotes 3. someone else accidentally removed the places in the editor shell where the editor type was being set, so we don't actually have a good record of whether we're a plaintext or html editor any more. All these things need to be fixed. I have at least partial fixes, which will be checked in as soon as the tree opens for M12.
Rich: I've checked in the fixes for the plaintext editor, and I've verified that if I change line 128 of nsMsgCompose.cpp from < if ( (aQuoted) && (aHTMLEditor) ) to > if ( (aQuoted) ) the message is quoted correctly, at least on Linux. Sending this bug back to you to decide whether it's kosher to check in that change to nsMsgCompose (should probably remove the comment, too :-). Or I can check it in if you'd rather, but I didn't want to check it in without your ok.
That would be great if you can check in the changes for nsMsgCompose.cpp. I'm knee deep in a compose back end issue so this would really help out. - rhp
Okay, taking the bug back, and I have checked in the changes and will close the bug.
