Using GPGTools on macOS, I signed a message that looks like this:
- List Item - Inner List Item
The signed message looks like this:
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 - - List Item - Inner List Item -----BEGIN PGP SIGNATURE----- ...
Any line that starts with a dash (not indented) gets prepended with
-␠ in the signed message. Why does GPG do that?
