[AD] Nested for_each_files()

[Shawn Hargreaves <shawn@xxxxxxxxxx>]

Does anyone care about being able to nest calls to for_each_file(), ie. 
being able to iterate through one set of files from inside the callback for 
another iteration?

If so, I'll need to change the Unix findfirst/findnext emulation to allow 
that, because at the moment it uses a global iteration state. Doing this 
properly would require an extra call, though, since the DOS findfirst 
interface has no shutdown call, wheras we would need one to close down a 
Unix opendir/readdir iteration, so I'm tempted not to bother, and just say 
that this function is not nestable. Anyone got any problems with that?
