-
-    Shelving takes files that "hg status" reports as not clean, saves
-    the modifications to a bundle (a shelved change), and reverts the
-    files so that their state in the working directory becomes clean.
-
-    To restore these changes to the working directory, using "hg
-    unshelve"; this will work even if you switch to a different
-    commit.
-
-    When no files are specified, "hg shelve" saves all not-clean
-    files. If specific files or directories are named, only changes to
-    those files are shelved.
-
-    In bare shelve (when no files are specified, without interactive,
-    include and exclude option), shelving remembers information if the
-    working directory was on newly created branch, in other words working
-    directory was on different branch than its first parent. In this
-    situation unshelving restores branch information to the working directory.
-
-    Each shelved change has a name that makes it easier to find later.
-    The name of a shelved change defaults to being based on the active
-    bookmark, or if there is no active bookmark, the current named
-    branch.  To specify a different name, use ``--name``.
-
-    To see a list of existing shelved changes, use the ``--list``
-    option. For each shelved change, this will print its name, age,
-    and description; use ``--patch`` or ``--stat`` for more details.
-
-    To delete specific shelved changes, use ``--delete``. To delete
-    all shelved changes, use ``--cleanup``.

+
+    Shelving takes files that "hg status" reports as not clean, saves
+    the modifications to a bundle (a shelved change), and reverts the
+    files so that their state in the working directory becomes clean.
+
+    To restore these changes to the working directory, using "hg
+    unshelve"; this will work even if you switch to a different
+    commit.
+
+    When no files are specified, "hg shelve" saves all not-clean
+    files. If specific files or directories are named, only changes to
+    those files are shelved.
+
+    In bare shelve (when no files are specified, without interactive,
+    include and exclude option), shelving remembers information if the
+    working directory was on newly created branch, in other words working
+    directory was on different branch than its first parent. In this
+    situation unshelving restores branch information to the working directory.
+
+    Each shelved change has a name that makes it easier to find later.
+    The name of a shelved change defaults to being based on the active
+    bookmark, or if there is no active bookmark, the current named
+    branch.  To specify a different name, use ``--name``.
+
+    To see a list of existing shelved changes, use the ``--list``
+    option. For each shelved change, this will print its name, age,
+    and description; use ``--patch`` or ``--stat`` for more details.
+
+    To delete specific shelved changes, use ``--delete``. To delete
+    all shelved changes, use ``--cleanup``.

+
+    If a shelved change is applied successfully, the bundle that

+    ``--continue`` to complete the unshelve operation. (The bundle
+    will not be moved until you successfully complete the unshelve.)

+    that causes a conflict. This reverts the unshelved changes, and
+    leaves the bundle in place.)
+
+    If bare shelved change (when no files are specified, without interactive,
+    include and exclude option) was done on newly created branch it would

+
+    After a successful unshelve, the shelved changes are stored in a

+    defaults to 10 but can be overridden using the ``shelve.maxbackups``
