Tag shorthand without <tag>

[CJ-Wright]

It seems I ran into an error

christopher@christopher-ubuntu ~/dev/xpdAcq tag $ rever 0.6.0
Activity 'version_bump' has already been completed!
activity-start:tag:starting activity tag
Updated tag '0.6.0' (was 066fd6e)

For posterity, this seems to be a git bug
