Hungarian people use Monday based weeks. This piece of information is not reflected in the current locale data. I attach the patch, please apply it. (Note: older Gtk/Gnome stuff asked the translators to tell the first day of the week, newer ones rely on libc providing this piece of information, so with official hu_HU locale the calendar starts on Sunday which is very hard to use for someone who is used to a Monday based one. This patch fixes this.)
Created attachment 685 [details] the proposed patch This is the proposed patch. As far as I know, the ";4" part is also okay, I did not just blindly copy it from other locales, the overlapping week counts to the year in which it has more days.
I changed it on the CVS trunk.
