When renovate attempts to process the dependencies for lyrebird, it attempts to
go to: https://gitlab.com/yawning/edwards25519-extra.git?go-get=1. For some
reason, that produces a redirect loop in gitlab, and it causes the renovate run
to fail after a redirect limit is reached. You can see the redirect yourself by
visiting that URL in your browser.

With this change, by simply removing the .git at the end, renovate would visit
https://gitlab.com/yawning/edwards25519-extra?go-get=1 and that does not produce
a redirect loop.

Also, updated the man page file.

readFull method takes byte slice as param instead of allocating one inside.
Advantage that caller is free to allocate slice or use const size array like:

var addr [net.IPv4len]byte
req.readFull(addr[:])
