# Merging from the command prompt will add diff markers to the files if there
# are conflicts (Merging from VS is not affected by the settings below, in VS
# the diff markers are never inserted). Diff markers may cause the following
# file extensions to fail to load in VS. An alternative would be to treat
# these files as binary and thus will always conflict and require user
# intervention with every merge. To do so, just uncomment the entries below
