I have noticed (Logstash 6.4.2) that the file exclude option in the file input plugin does not handle files with dots in the filename.....

e.g. aaa.bbbb-ERRORS-yyyy-mm-dd.log

these work:

```
path => ["C:/Elastic/TestAppLogs/*.log"]
exclude => "*-ERRORS-*"

path => ["C:/Elastic/TestAppLogs/*.log"]
exclude => "*bbbb-ERRORS-*"

```

But including the '.' in the filter of the name doesn't match and therefore it is included in the input:

```
path => ["C:/Elastic/TestAppLogs/*.log"]
exclude => "aaa.bbbb-ERRORS-*"
```
