* small fix for the config file. The parser assumes that the config file is
divided into sections (a section is the config data for a plugin and begins
with something like [foo]), so the comment for the beginning of the section
must be after the section marker and not before.
If you want to illustrate the problem (without this fix):
- save vlc's config
- exit from vlc and remove for example the dsp plugin (rm plugins/dsp.so)
- resave vlc's config
and now look at the end of the config file, it's all screwed up.
