Yes, in looking at the code: pretty stupid. In some error cases it uses
the keyword, but in the normal case, it always prompts. I'll fix that.

The problem with FileSets is that if there are multiple ones, Bacula
must select the correct one. The current implementation is not very user
friendly because in my head I was slightly confused between different
filesets and changed filesets.  For different FileSets (i.e. base name
different), Bacula must ask, but for changed FileSets (same base name,
just perhaps modified one or more times), there really is no reason to
ask the users.  I'm going to modify the code to be based on the "base
FileSet name" (i.e. the name that appears on the FileSet "Name"
directive). If there is only one FileSet, there will be no need to
prompt, if there are multiple ones, you will get a choice of the base
names.
