The reflog is useful in various git commands, to specify the old value
of a reference. For example, `HEAD@\{2\}` means "where HEAD used to be
two moves ago", `master@\{one.week.ago\}` means "where master used to
-point to one week ago", and so on. See linkgit:git-rev-parse[1] for
+point to one week ago", and so on. See linkgit:gitrevisions[7] for
more details.
To delete single entries from the reflog, use the subcommand "delete"
refs.

This computation involves traversing all the reachable objects, i.e. it
-has the same cost as 'git-prune'. Fortunately, once this is run, we
+has the same cost as 'git prune'. Fortunately, once this is run, we
should not have to ever worry about missing objects, because the current
prune and pack-objects know about reflogs and protect objects referred by
them.
