It is the other way around.  "git am" may be OK with "-t" (or it may
not--I do not know yet), but other commands that are currently
unaware of "interpret-trailers" (cherry-pick, revert, etc.) may have
better uses for a short-and-sweet 't'.

In the ideal future, "interpret-trailers" should not have to exist
in the end-users' vocabulary, as all the front-line end-user facing
programs would be aware of it.  But we are not there.

Letting it reserve a short-and-sweet 't' that allows it to dictate
that its callers must have the same 't' is tail wagging the dog that
I want to avoid.
