Turns out many single-letter specifiers are already taken.
I've used the following:

---

 %Tt = the strings 'normal' or 'signalled' or 'stopped' based on how
            the program exited.
 %Tx = numeric exit code IF the program exited normally (not signalled).
       empty otherwise.
 %Tn = numeric signal number IF the program was terminated by a signal.
       empty otherwise.
 %Ts = signal name IF the program was terminated by a signal.
       empty otherwise.
---

Examples:

 $ ./time -q \
            -f "exit type: %Tt\nexit code: %Tx\nsig-spec: 
%Ts\nsig-num:%Tn\n" \
                 ./tests/time-aux -S KILL -e 4
      exit type: signalled
      exit code:
      sig-spec: KILL
      sig-num: 9

      $ ./time -q \
            -f "exit type: %Tt\nexit code: %Tx\nsig-spec: %Ts\nsig-num: 
%Tn\n" \
                 ./tests/time-aux -e 4
      exit type: normal
      exit code: 4
      sig-spec:
      sig-num:

---

The code is available in a separate branch:
   https://git.savannah.gnu.org/cgit/time.git/log/?h=signal-reporting

and here:

https://download-mirror.savannah.gnu.org/releases/time/time-1.9.5-4aa7.tar.gz

---

More testing and feedback is welcomed.

Once this stabilizes I'll add it to the GNU time master branch.
