Did you purposely miss the one in line number 278 of
builtin/show-branch.c because I think you only touched up the parts
which were related to "refs/" but didn't explicitly mention it in the
commit message?
if (starts_with(pretty_str, "[PATCH] "))
pretty_str += 8;
If not, you can squash this patch attached. Sorry, couldn't send it in
mail because of proxy issues.
