Dangling objects are not a problem. At worst they may take up a little
extra disk space. They can sometimes provide a last-resort method for
-recovering lost work--see <<dangling-objects>> for details. However, if
-you wish, you can remove them with linkgit:git-prune[1] or the `--prune`
-option to linkgit:git-gc[1]:
-
--------------------------------------------------
-$ git gc --prune
--------------------------------------------------
-
-This may be time-consuming. Unlike most other git operations (including
-git-gc when run without any options), it is not safe to prune while
-other git operations are in progress in the same repository.
-
-If linkgit:git-fsck[1] complains about sha1 mismatches or missing
-objects, you may have a much more serious problem; your best option is
-probably restoring from backups. See
-<<recovering-from-repository-corruption>> for a detailed discussion.

If you are interested in more details of the revision walking process,
just have a look at the first implementation of `cmd_log()`; call
-`git-show v1.3.0~155^2~4` and scroll down to that function (note that you
+`git-show v1.3.0{tilde}155^2{tilde}4` and scroll down to that function (note that you
no longer need to call `setup_pager()` directly).
Nowadays, `git log` is a builtin, which means that it is _contained_ in the
