I don't think I would regret it at all.  I do not expect to conflate the
word "tokens" with the meaning "show-tree-state".  It only has this
meaning because it is part 'git status'.  If I want to show a different
kind of tokens in the future, I think "--tokens" would still work fine
there.  It would even have precedent.

Consider the usage:

  git status   # show work-tree status
  git status --short  # show short work-tree status
  git status --tokens  # show work-tree status in token form

In the future if someone adds a similar operation to another command,I
do not think it would be confusing if it had a similar result. 

  git log --tokens
  git show-ref --tokens HEAD

But maybe "--tokens" has some better meaning that someone will want to
use in the future.  I'm not married to it.  But "git status" already
means "Show the working tree status".  So "git status --show-tree-state"
sounds redundant or meaningless.

'git status' already recognizes switches --ignored and --branch, for
example, to add extra state information to the output.  I want to add
"tree-state tokens" to the list.  But I don't know a better name for them.

Perhaps "--show-tree-state" is sufficient.  Still sounds redundant to me.
