comments in a key file

["Tshepang Lekhonkhobe" <tshepang gmail com>]

Looking here:
http://developer.gnome.org/doc/API/2.0/glib/glib-Key-value-file-parser.html

under the section describing differences between .ini files and key
files I find this:
* Key files allow only comments before the first group.

I saw a typical key file and found comments could be put anywhere. Am
I missing anything?
