Your script can loop, trying one command and if that fails try the
other.

Take your example of "moving a tag". If I try to move a tag and it
does not exist I probably mistyped the tag name, so the command should
fail rather than create the wrong tag. If I try to create a tag that
already exists I probably mistyped the tag name, so the command should
fail rather than overwrite the tag. How often do you move or create a
tag and not know whether or not it exists? If other people are
creating/removing tags that conflict with yours do you really want to
overwrite them?
