OK, so in short, the trailer subsystem matches the second level of
the configuration variable name (e.g. "Acked") in a case insensitive
way, and it does *not* normalize the case in the output.  The .key 
request is a mechanism to replace the matched key with the specified
string, so there is *NO* case normalization in what Anders observed.

In other words,

  $ printf '\naCKed: Zz\n' | \
    git -c 'trailer.Acked.key=Rejected' interpret-trailers --parse

would have emitted "Rejected: Zz".
