Make tests and man page examples match
Make the tests test_manual_page_example[1-5] match exactly what is
written in the manual page, and add comments to manual page as
reminders to keep tests and manual page examples in sync.
* mandos-ctl (Test_commands_from_options.test_manual_page_example_1):
Remove "--verbose" option, since the manual does not have it as the
first example, and change assertion to match.
* mandos-ctl.xml (EXAMPLE): Add comments to all examples documenting
which test function they correspond to. Also remove unnecessary
quotes from option arguments in fourth example, and clarify language
slightly in fifth example.
