filename for signature file in GPGOL

The signature is stored in a file called “unnamed”, which is weird for users with no signature management embedded in their email client seeing a strange file attached to an inbound mail. Is it possible to configure the file name for the signature so it is something like signature.asc or similar?

Good point. We should name it signature.asc

Task for this is: https://dev.gnupg.org/T4258
