cumulative patches suck. don't do them unless necessary (yes, svn makes
them necessary more often than one'd like it to, but not in this case).

yes. you should have tracked the kconfig_new_take2 branch. ;)

pasting the patch wasn't particularly clever ... the line breaks don't
exactly help applying or reading it. :}
btw, gmail's mime type detection works for me - maybe the windows
lineendings were at fault or maybe gmail uses a mime type delivered by
the browser - dunno.

that doesn't test that the entry is gone, though.
i guess copying the startsWith("devices|") counter and comparing with
one would make more sense.

wow, this was impressively broken - locale appended after the key was
decoded.

while trying to understand the rest of the patch i noticed that
EntryDefault isn't set anywhere. consequently all the logic building on
top of it is dysfuct. so there is little point in reviewing the patch,
i figure.

procedure:
- revert everything
- do the localized entry purge, commit
- add the failing tests (possibly come up with more?), commit
- fix cascaded parsing. revisit the problems. if they persist, post a
  new patch.
