Yeah, but it can take many characters, not just one.
For example you might want to do something like:

seps=$(git config trailer.separators)
test -z "$seps" && seps=':'
git -c trailer.separators="|$seps" interpret-trailers --parse infile >outfile

So that the output uses '|' as a separator.

Changing the default separator as shown above, should make it easier
to parse the result.
