Env-flags are "flags" that can only be set by env var (see caveat below).
All of the real flags have a corresponding env-flag (kind of, but not
really). The real goal was to deprecate `--password` but keep the env
var as a documented interface.
This does that (though --password still works) and updates the usage and
manual.
This allows some future work to follow the pattern. We do not register
every CLI flag as an env-flag because the help text would be
duplicative. This probably wants a wrapper API that allows declaring of
abstract flags, with CLI, env, or both sources.
Caveat:
ACTUALLY, these still have a flag, but the flag is specially named and
hidden. This makes testing a little easier where passing flags is
handled well but env vars is not.
github actions fails with an error about "--ip can only be used on
user-defined subnets". It looks like `--ip` never worked properly, but
wasn't a hard error before.
This is a simpler alternative to
11f475229692da93dff4d8a9337c5fc9cc48e51a (included below), which tried
using docker networks. It seems to work but is complicated and can leak
resources. Needs more work.
Instead, this commit just swaps out the `nc` response script
on the fly, rather than restarting `nc` and trying to get the same IP.

Rather than hugo, which I really don't know much about and don't care to
maintain, it now is just a trivial HTTP server (python) serving content
from this repo.
Old way:
- ls-remote $ref $ref^{} and parse
- compare to current
- if changed, fetch
- update worktree
New way:
- fetch $ref
- compare to current
- if change, update worktree
