Since 1.78, when compiling a terrain that makes use of Arma 3 plants_f/Bush/*.p3d models the compiler generates warnings of trailing spaces in named properties for 7 of the models.

This is not an exhaustive list from the entire p:\a3 folder, only the plants_f folder.
There may well be more in other folders and is probably an encoding error from a platform upgrade.
