What I was thinking of was something like this :
struct strbuf format = STRBUF_INIT;
char c = ' ';
if (current)
c = '*';
strbuf_addf(&format, "%c....", c, other format options...);
show_ref_array_item(item, format.buf, quote_style, 0);
strbuf_release(&format);
This would remove the need of making the printing of the "*" to be
needed by ref-filter. As this is only needed in branch.c
If going on what you're saying we could have a "%(starifcurrent)" atom or
something, but I don't see a general use for this.
