in_tail: State the difference in exclude_path and path formats

[captn3m0]

Caused me to write the following:

path ["/var/log/apache2/*.access.log", "/var/log/apache2/access.log"]

Might be worth making it a bit more explicit perhaps?

@captn3m0 OK. I have merged your patch.

FWIW, a point worth noting here is that you do not need to use an array notation for exclude_path. This means that the following configuration is perfectly valid:

<source>
  @type tail
  path /var/log/httpd/*
  exclude_path /var/log/httpd/*.gz, /var/log/httpd/*.zip
</source>
