What does this mean ?
* * MIRROR ABORTED! * *
The current temporary cache is required for any update operation and only
contains data downloaded during the present aborted session.
The former cache might contain more complete information; if you do not want
to lose that information, you have to restore it and delete the current
cache.
This can easily be done here by erasing the hts-cache/new.* files]

Whats the meaning of this dialog that displays after every interrupted session
?
1. Since its confusing and contradicting itself. Stating that *if* you want to
keep the former cache you have to restore it, and delete the current one. It
then points you to the dir. *new files* thinking logically, that the word
"new" could imply the new cache, not the old one.

2. WHy would a user wish to *restore* the old cache ?  If the user has
downloaded more than they have previously, then it makes sense to keep the
current one.. Likewise, if they have downloaded less than the previous, then
the user can just do an "Update existing"
