Customising markdown syntax highlighting in Geany

I'm using Geany 1.23.1 on Lubuntu 13.10. I've copied over filetypes.markdown from /usr/share/geany to ~/.config/geany/filedefs. filetypes.markdown has the following content: # For complete documentation of this file, please see Geany's main documentation [styling] # Edit these in the colorscheme .conf file instead default=default strong=string_3 emphasis=string_4 header1=keyword_1 header2=keyword_1 header3=keyword_1 header4=keyword_1 header5=keyword_1 header6=keyword_1 ulist_item=tag_unknown olist_item=tag_unknown blockquote=tag_unknown strikeout=tag_unknown hrule=tag_unknown link=keyword_1 code=attribute_unknown codebk=attribute_unknown [settings] # default extension used when saving files extension=mkd # sort tags by appearance symbol_list_sort_mode=1 Why is the third line present: **# Edit these in the colorscheme .conf file instead**? What is wrong with editing filetypes.markdown itself? I would think that, at least from a user's perspective, editing ~/.config/geany/filedefs/filetypes.markdown (or any other filetypes file) would be preferable to editing a .conf file (in ~/.config/geany/colorschemes) as suggested because editing a .conf file would affect all filetypes not just filetype.markdown.
