For loop detection, a history is mandatory. In the process of also adding a flexible struct to recurse, the recurse-definition was moved to fs.h. The motivation behind the struct is to allow easy extensions to the recurse-function without having to change the prototypes of all functions in the process. Adding flags is really simple as well now. Using the recursor-struct, it's also easier to see which defaults apply to a program (for instance, which type of follow, ...). Another change was to add proper stat-lstat-usage in recurse. It was wrong before.
