Document --stale-fix, used in "git reflog expire --stale-fix --all"
to remove invalid reflog entries, to fix situation after running
non reflog-aware git-prune from an older git in the presence of
reflogs (see RelNotes-1.5.0.txt).

Based on description of commit 1389d9ddaa

OPTIONS
-------
--stale-fix::
This revamps the logic -- the definition of "broken commit"
becomes: a commit that is not reachable from any of the refs and
there is a missing object among the commit, tree, or blob
objects reachable from it that is not reachable from any of the
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
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.
--expire=<time>::
Entries older than this time are pruned. Without the
option it is taken from configuration `gc.reflogExpire`,
