   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.
   
       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".
   
   (use "hg help -e shelve" to show help for the shelve extension)
   
   options ([+] can be repeated):
   
    -A --addremove           mark new/missing files as added/removed before
                             shelving
       --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
    -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               show patch
    -i --interactive         interactive mode, only works while creating a shelve
       --stat                output diffstat-style summary of changes
    -I --include PATTERN [+] include names matching the given patterns
    -X --exclude PATTERN [+] exclude names matching the given patterns
       --mq                  operate on patch repository

 "hg unshelve" at REV5 implies steps below:
 
 (1) commit changes in the working directory (REV6)
 (2) unbundle shelved revision (REV7)
 (3) rebase: merge REV7 into REV6 (REV6 => REV6, REV7)
 (4) rebase: commit merged revision (REV8)
 (5) rebase: update to REV6 (REV8 => REV6)
 (6) update to REV5 (REV6 => REV5)
 (7) abort transaction
