unshelve: forget unknown files after a partial unshelve

This is a follow-up patch to 6957f7b93e03. This allows hg to forget
unknown files after a partial unshelve.

 """save and restore changes to the working directory
 
 The "hg shelve" command saves changes made to the working directory
 and reverts those changes, resetting the working directory to a clean
 state.
 
 Later on, the "hg unshelve" command restores the changes saved by "hg
 shelve". Changes can be restored even after updating to a different
 parent, in which case Mercurial's merge machinery will resolve any
 conflicts if necessary.
 
 You can have more than one shelved change outstanding at a time; each
 shelved change has a distinct name. For details, see the help for "hg
 shelve".

   hg shelve [OPTION]... [FILE]...
   
   save and set aside changes from the working directory
   
       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".
   
   options ([+] can be repeated):
   
    -A --addremove           mark new/missing files as added/removed before
                             shelving
    -u --unknown             store unknown files in the shelve
       --cleanup             delete all shelved changes
       --date DATE           shelve with the specified commit date
    -d --delete              delete the named shelved change(s)
    -e --edit                invoke editor on commit messages
    -k --keep                shelve, but keep changes in the working directory
    -l --list                list current shelves
    -m --message TEXT        use text as shelve message
    -n --name NAME           use the given name for the shelved commit
    -p --patch               output patches for changes (provide the names of the
                             shelved changes as positional arguments)
    -i --interactive         interactive mode
       --stat                output diffstat-style summary of changes (provide
                             the names of the shelved changes as positional
                             arguments)
    -I --include PATTERN [+] include names matching the given patterns
