** COMMAND: update
**
** Usage: %fossil update ?OPTIONS? ?VERSION? ?FILES...?
**
** Change the version of the current checkout to VERSION. Any
** uncommitted changes are retained and applied to the new checkout.
**
** The VERSION argument can be a specific version or tag or branch
** name. If the VERSION argument is omitted, then the leaf of the
** subtree that begins at the current version is used, if there is
** only a single leaf. VERSION can also be "current" to select the
** leaf of the current version or "latest" to select the most recent
** check-in.
**
** If one or more FILES are listed after the VERSION then only the
** named files are candidates to be updated, and any updates to them
** will be treated as edits to the current version. Using a directory
** name for one of the FILES arguments is the same as using every
** subdirectory and file beneath that directory.
**
** If FILES is omitted, all files in the current checkout are subject
** to being updated and the version of the current checkout is changed
** to VERSION. Any uncommitted changes are retained and applied to the
** new checkout.
**
** The -n or --dry-run option causes this command to do a "dry run".
** It prints out what would have happened but does not actually make
** any changes to the current checkout or the repository.
**
** The -v or --verbose option prints status information about
** unchanged files in addition to those file that actually do change.
**
** Options:
** --case-sensitive <BOOL> override case-sensitive setting
** --debug print debug information on stdout
** --latest acceptable in place of VERSION, update to latest version
** --force-missing force update if missing content after sync
** -n|--dry-run If given, display instead of run actions
** -v|--verbose print status information about all files
** -W|--width <num> Width of lines (default is to auto-detect). Must be >20
** or 0 (= no limit, resulting in a single line per entry).
