expression, which will make repositories want to move files around as
necessary in order to get fully balanced.
Using this in a perferred content expression makes git-annex need to do
some additional work to keep track of how full repositories are. Usually
that won't affect performance much. However, the first time git-annex
processes this in a given git repository, it will need to examine
all the locations of all files, which can be slow when there are a lot of
them. When this causes git-annex to do a lot of work, it will
display "(calculating repository sizes)".
Note that `not balanced` is a bad thing to put in a preferred content
expression for the same reason `not present` is.
