If you can put energy into this, I suggest you improve pretty.c a bit,
adding new format_ref_message(), similar to format_commit_message(),
except that it takes a ref. You can extend "struct
format_commit_context" to contain what "struct refinfo" does. I think
pretty.c only lacks a few specifiers that for-each-ref has. I think I
mentioned it in my for-each-ref series already, but we need to think
how to specify "align to the left with the best width" and how
format_ref_message() can figure the width out. A callback function
might do.
