Hi,
I've noticed that some Doxygen keywords are not properly highlighted when editing a .c or .cpp file with Geany. So I propose a patch for 'filetypes.cpp', 'filetypes.c', and so on... to correct this. The new list of Doxygen keywords is taken from Doxygen documentation (http://www.stack.nl/~dimitri/doxygen/commands.html).
BTW, thanks for your job on Geany. This soft is really nice to work with.
