The dot must follow the machine ID immediately, let's check for that.
Also, I think it's generally better to parse the machine ID and then
comparing it, instead of comparing the string representation. That's
more in line how we usually do it, as we parse 128bit IDs generally
case-insensitively.
The common case will be that no namespaces are defined, hence by default
we'd just output "NAMESPACE" and exit, which is very confusing.
Generate a nice message instead, how many of our tools do it. Suppress
it on --quiet however.
Previously, 'udevadm control' only checked the number of the arguments.
So, if only `--timeout` is specified, it spuriously did nothing and succeeded.
This makes the command request at least one control command.
This mimics what we do for systemd-cryptsetup@.service (see
src/shared/generator.c), and makes sense since repart might lock up the
root volume against a TPM, which ideally has its SRK already set up by
then.
More importantly though, this ensures that we ordered correctly after
tpm2.target (which systemd-tpm2-setup-early.service has a dependency
on), for systems where the TPM drivers are not compiled into the kernel.

* fix error
* remove options that are no longer supported
* add missing options
* stop completion if an option `--help` or `--version` is supplied

zjs: a note for the reader:
zshcompsys(1) in the section about optspecs in _arguments says:
> Each of the forms above may be preceded by a list in parentheses of option names and argument num‐
> bers. If the given option is on the command line, the options and arguments indicated in parentheses
> will not be offered. For example, ‘(-two -three 1)-one:...' completes the option ‘-one'; if this ap‐
> pears on the command line, the options -two and -three and the first ordinary argument will not be
> completed after it. ‘(-foo):...' specifies an ordinary argument completion; -foo will not be com‐
> pleted if that argument is already present.
>

> (i.e. a specification of the form ‘\*:...'); a colon (:) for all normal (non-option-) arguments; and a

The intended effect of the change is to remove irrelevant completion matches from the completion.
tl;dr: (- : ) prevents further completion
