Comparing the results of id3tag to the results of taglib: 3 potential bugs

[Xavier Duret]

It seams the webmail I am using is worse than I thought. In the past,
it was just doing some reformating. Now, it ate most of this email. A
legacy from university... I am done with this Lycos junk webmail. I
created a gmail address for maillists. Sorry for the inconvenience.

Here is the tag extracted from one of the files that has duplicated genre:

Brian was right. So there is a problem.

Scott was right. So there is no problem.

Here is the tag extracted from one of the files that has trailing
space in the different fields.

Brian was wrong. It is a problem of difference of interpretation of
ID3v1.1 between whatever junk produced this file and taglib. The
question is should taglib handle it gracefully.
