[log][paranoia][wrong] Chasing Encryption was: age

[Undiscussed Horrific Abuse, One Victim & Survivor of]

grarpamp's email address proposed a way to sign messages using age.
You publicise a private key, and encrypt hashes to it.

age ostensibly has a way to generate public keys from private keys, in
this commit, haven't looked:
https://github.com/FiloSottile/age/commit/f31d4eca473cb904174bc3658f84dbc1b6dc195d

seems it would be fun to use the message signing approach. My local
age is version 1.0.0~rc1 and does not yet have the -y option needed
for making the encrypted signatures.

$ age --version
1.0.0~rc1

I seem to already have a ~/src/age folder with git sources, so I tried
to pull the latest changes and rebuild. Unfortunately, the latest
changes are a different codebase from mine:

ubuntu at ubuntu:~/src/age $ git remote -v
origin  https://github.com/FiloSottile/age.git (fetch)
origin  https://github.com/FiloSottile/age.git (push)
ubuntu at ubuntu:~/src/age $ git pull
fatal: refusing to merge unrelated histories

It turns out my repo was on the master branch, which has somehow had
its history entirely rebased. Whereas the branch renamed to main, has
history that aligns with my history.

$ git merge origin/main # fast-forwards fine
$ git checkout -b main
$ git merge origin/master # fails, unrelated histories

    cmd/age: offer a hint when the file was corrupted by PowerShell

    I would still like to find a way to offer a warning while doing the
    encryption, rather than at decryption time, but better than nothing.

    Updates #290

However!, unfortunately:

ubuntu at ubuntu:~/src/age $ git log f31d4eca473cb904174bc3658f84dbc1b6dc195d
fatal: bad object f31d4eca473cb904174bc3658f84dbc1b6dc195d

The commit containing the -y option does not appear to be on any of
the branches the server sent. I'm sure it is somewhere!
