It seems to us that the maximum external link depth is
buggy right now:
If no parameter is set, then the program works well with
only the specified domain (>1000 files saved to disk).
If parameter is set to 1, then the program only saves 5
files (from the same domain) to disk !
It looks like this is the same behaviour as "maximum
mirroring depth", the programm doesn't seem to make a
difference between interal (overall) or external links...
