** Show the difference between the current version of each of the FILEs
** specified (as they exist on disk) and that same file as it was checked
** out.  Or if the FILE arguments are omitted, show the unsaved changed
** currently in the working check-out.
**
** If the "--from VERSION" or "-r VERSION" option is used it specifies

** The "-i" command-line option forces the use of the internal diff logic
** rather than any external diff program that might be configured using
** the "setting" command.  If no external diff program is configured, then
** the "-i" option is a no-op.  The "-i" option converts "gdiff" into "diff".
**
** The "-N" or "--new-file" option causes the complete text of added or
** deleted files to be displayed.
**
** Options:
**   --from|-r VERSION   select VERSION as source for the diff
**   --new-file|-N       output complete text of added or deleted files
**   -i                  use internal diff logic
**   --to VERSION        select VERSION as target for the diff
