Reduce "$GPG_TTY unset" message to one line and highlight as a warning.
It's possible that gpg will work fine without $GPG_TTY being set (e.g., when using a GUI pinentry program). Therefore, the message should be classified as a warning, not an error. Also, use a single :echom to ensure the user sees the entire message, not just "gpg-agent might not work." First part of GH #1 Signed-off-by: James McCoy <vega.james@gmail.com>
