In some cases, it could be that the user is having a problem with an
object which isn't present in their normal object directory. We can get
a hint that that might be the case by examining the list of alternates
where their object may be stored instead. Since paths to alternates may
be sensitive, we'll instead count how many alternates have been
specified and note how many of them exist or are broken.
