The list of example files in README is only a fraction of the ones Geany supports, its not intended to be an exhaustive list, so I don't see the point of adding any particular language to it and its long enough now.
Adding the reminder that libvte is needed for the terminal is ok, but I'm not sure it shouldn't be in INSTALL??
There is a message in `Help->Debug Messages` when libvte isn't found (or which is loaded if it is found) so I don't see a point of adding it to status. If anything goes wrong the debug messages is where you should look, not everything should go in status.
