Yes we need to think about how to do it in a way that is helpful for 
things like Reviewed-by: or Tested-by: but does not break other 
workflows. One possibility would be to have a 
trailer.<name>.defaultValue config key but I'd be interested in other 
people's ideas.

One other idea is that "git commit --author Kristoffer" will search 
recent commits for matching author to obtain your full name and email 
address. Something like that could be useful for expanding values 
--tailer=Co-Authored-by" or perhaps we could teach the completion script 
to suggest suitable completions based on some config describing the 
values we expect for certain keys.

I think it is because with define GIT_*_IDENT to include the timestamp 
to match the ident lines in commit and tag objects. You can always trim 
the timestamp appending something like "| sed 's/[^>]*$//'".
