Subject: [metadatafromtitle] Some improvements and cleanup
X-Git-Url: http://git.oshgnacknak.de/?a=commitdiff_plain;h=88cf6fb3685c4e012c9f574cbc5f1836c42fc06d;p=youtube-dl

[metadatafromtitle] Some improvements and cleanup

* Remove the 'songtitle' field, 'title' can be used instead.
* Remove newlines in the help text, for consistency with other options.
* Add 'from __future__ import unicode_literals'.
* Call '__init__' from the parent class.
* Add test for the format_to_regex method
