gopass: Inconsistency for newlines

Hi. I have an issue with msmtp which requires me to add ; echo at the end of passwordeval "gopass show -f mail", otherwise, I get the following error:

msmtp: output of 'gopass show -f mail' is longer than 500 characters, or is not terminated by newline

I think it’s because the newline is not output when it’s not in a tty. I think it would be better to have a consistent behavior to avoid this issue. Thanks.
