4 is correct. For some time now, there is an additional file containing
the URL -> UUID / file name mapping among other things. Thus, the "clear
cache" number is correct in that it will delete all 5 files but not
all of them are actually individual repository log caches ...

On the other hand, this is the only way to clean it entirely and
to work around any problems there may be with the cache management.

Yea, that would be good. We should add an "are you sure?" box and
maybe replace "probably deleted repository" by "URL not known" which
is closer to the truth.

I was incorrect with assuming that the main reason for those UUID
entries would be deleted repositories. In fact, they just mean that
the repositories.dat file does not contain a suitable URL entry.
So, that means repositories.dat has been deleted some time ago and
some repositories have not been accessed since then.

There was a format change to this file few weeks ago rendering the
old one obsolete. This should not happen again for a very long time ;)

Yes. I am not even sure that it does what I expect it to do:
fetch all missing data, including user revprops. It seems the
latter will cause the slowdown but are not stored in the cache
afterwards (number of revisions with incomplete user revprop
info does not change). I will have look at this.
