Let me take this one back; we do a moral equivalent when we create a
tag, like this:
strbuf_addf(sb, "refs/tags/%s", name);
return check_refname_format(sb->buf, 0);
So validating using check_refname_format() is indeed a very good
thing to do.
As you have length and buffer here, I would suggest updating this
part of your patch to print into a strbuf
strbuf_addf(&sb, "refs/tags/%.*s", (eol - buffer), buffer);
if (check_refname_format(sb.buf))
ret = ...
and keep the constness of the incoming data.
