Commit Message

John Cai Jan. 5, 2022, 10:59 p.m. UTC 
From: John Cai <johncai86@gmail.com>

Introduce a --annotate-stdin that is functionally equivalent of --stdin.
--stdin does not behave as --stdin in other subcommands, such as
pack-objects whereby it takes one argument per line. Since --stdin can
be a confusing and misleading name, rename it to --annotate-stdin.

This change adds a warning to --stdin warning that it will be removed in
the future.
