In preparation for adding consistent "%(trailers)" atom options to
`git-for-each-ref(1)`'s "--format" argument, change "%(trailers)" in
pretty.c to separate sub-arguments with a ",", instead of a ":".
Multiple sub-arguments are given either as "%(trailers:unfold,only)" or
"%(trailers:only,unfold)".
This change disambiguates between "top-level" arguments, and arguments
given to the trailers atom itself. It is consistent with the behavior of
"%(upstream)" and "%(push)" atoms.
