I'm torn about the new remove_everything_inside_dir(). Obviously it's a
copy-paste-modify of dir.c:remove_dir_recursively(), and could instead be
implemented by adding an extra flag to remove_dir_recursively(). However,
adding a "#define REMOVE_DIR_CONTENTS_BUT_NOT_DIR_ITSELF 04" seemed even
uglier to me...
Hmm, what ugliness am I missing when viewing the attached patch? It looks
simple and straightforward enough, at least to me.
