This would be cleaner, and more easily extended to other cases if you
used a 'to_free' variable. For instance, something like this:
const char *desc = item-name;
char *to_free = NULL;
...
case REF_DETACHED_HEAD:
...
desc = to_free = get_head_description();
break;
...
strbuf_addf(name, %s%s, prefix, desc);
...
free(to_free);
This looks neater!
Note that it's safe to free 'to_free' when it's NULL, so you don't
need to protect the free() with that ugly specialized 'if' which
checks for REF_DETACHED_HEAD. You can also do away with the cast to
non-const when freeing.
Yea makes sense will change to what you suggested.

[PATCH 04/10] branch: roll show_detached HEAD into regular ref_list
Remove show_detached() and make detached HEAD to be rolled into
regular ref_list by adding REF_DETACHED_HEAD as a kind of branch and
supporting the same in append_ref(). This eliminates the need for an
extra function and helps in easier porting of branch.c to use
ref-filter APIs.
Before show_detached() used to check if the HEAD branch satisfies the
'--contains' option, now that is taken care by append_ref().
