Windows 10 command line `ssh-keygen -b 2048 -mPKCS8` doesn't change the `.pub` file created to PKCS8 (it's always the one-liner).

I can do this to get the actual format output to the screen:
`ssh-keygen -ef test.key -mPKCS8`

but if I tell it to use `PKCS8` when generating, it seems to ignore it?

Is this as intended or a bug or am I doing something wrong?

TIA!!
