Function ListR

fs/walk/walk.go:149–164

ListR lists the directory recursively. If includeAll is not set it will use the filters defined. If maxLevel is < 0 then it will recurse indefinitely, else it will only do maxLevel levels. If synthesizeDirs is set then for bucket-based remotes it will synthesize directories from the file structur
