I often compose my email messages in Word and then paste them into the message box for an outgoing email. In Mavericks, if I just pasted, Mail inserted an extra line feed between paragraphs. If I did a Paste and Match Style then I didn't get the extra line feeds. However, now that I am in Yosemite, the extra line feeds are inserted for Paste and also for Paste and Match Style. This is true whether I use plain text format or RTF. How can I suppress the extra line feeds?
