Are 'shorten', 'track', and 'trackshort' mutually exclusive? If so, a
simple enum would be clearer than bitfields:
union {
const char *color;
struct align align;
enum { RR_PLAIN, RR_SHORTEN, RR_TRACK, RR_TRACKSHORT }
remote_ref;
};
Or something.

"align:"? Also, how about a more grammatically-friendly error message?

Tangent: These xstrfmt()'d strings are getting leaked, right? Is that
something that we need to worry about (if, for instance, a repository
contains a lot of tracking refs)? Should there be a NEEDSWORK comment
here regarding the issue?

Is this duplicating work already done by fill_remote_ref_details()?
