Merge branch 'ss/user-manual' into maint

Drop a few old "todo" items by deciding that the change one of them
suggests is not such a good idea, and doing the change the other
one suggested to do.

* ss/user-manual:
  user-manual: add addition gitweb information
  user-manual: add section documenting shallow clones
  glossary: define the term shallow clone
  user-manual: remove temporary branch entry from todo list

+How to get a Git repository with minimal history
+------------------------------------------------
+
+A <<def_shallow_clone,shallow clone>>, with its truncated
+history, is useful when one is interested only in recent history
+of a project and getting full history from the upstream is
+expensive.
+
+A <<def_shallow_clone,shallow clone>> is created by specifying
+the linkgit:git-clone[1] `--depth` switch. The depth can later be
+changed with the linkgit:git-fetch[1] `--depth` switch, or full
+history restored with `--unshallow`.
+
+Merging inside a <<def_shallow_clone,shallow clone>> will work as long
+as a merge base is in the recent history.
+Otherwise, it will be like merging unrelated histories and may
+have to result in huge conflicts.  This limitation may make such
+a repository unsuitable to be used in merge based workflows.
