The new-email trigger now uses templates instead of %-based placeholders.

Your configuration in this instance was automatically converted to:

[triggers]
new-email = ` + format.ShellQuote(Triggers.NewEmail) + `

Your configuration file was not changed. To make this change permanent and to
dismiss this warning on launch, replace the above line into aerc.conf. See
aerc-config(5) for more details.

The automatic conversion of new-email will be removed in aerc 0.17.
