Is it a normal situation to have refname==NULL, or is it something
worth reporting as an error?
Without passing the &flag argument, I do not think there is a
reliable way to ask resolve_ref_unsafe() if "HEAD" is a symbolic
ref.
int flag;
const char *refname = resolve_ref_unsafe("HEAD", 0, NULL, &flag);
const char *branchname;
if (!refname)
die(...);
else if (!(flag & REF_ISSYMREF))
return; /* detached HEAD */
else if (skip_prefix(refname, "refs/heads/", &branchname))
puts(branchname);
else
die("HEAD (%s) points outside refs/heads/?", refname);
or something like that?
