dmypy run keeps rerunning when using certain glob styles

[rggjan]

With a configfile like this:

...
[mypy-abc.*]
...

dmypy run works fine, and only reruns when the configfile changes.

However, when I change the module configuration to:

...
[mypy-abc.*.abc]
...

dmypy keeps rerunning, saying:

Restarting: configuration changed
Daemon stopped
Daemon started

even without further changes to the config file.

I tried to track the error down, and changed the error message indmypy_server.py to:

    def cmd_run(self, version: str, args: Sequence[str],
                is_tty: bool, terminal_width: int) -> Dict[str, object]:
        """Check a list of files, triggering a restart if needed."""
            ...
            # Signal that we need to restart if the options have changed
            if self.options_snapshot != options.snapshot():
                return {'restart': 'configuration changed' + str(self.options_snapshot) + '===' + str(options.snapshot())}
            ...

Comparing self.options_snapshot with options.snapshot(), I can see that with the second config file, self.options_snapshot contains this:

'glob_options':
[('abc.*.abc',
re.compile('abc(\\..*)?\\.abc\\Z'))],

while options.snapshot() contains this:

'glob_options':
[],

So I believe something is wrong in this case...
