The helper has only one caller, which makes me wonder why we do not
have to call it more often.  If "git checkout" or "log -p" notice an
attribute file is updated, I wonder they should call it, for
example.  But of course this is completely out of scope of this
topic.

This has been leaking even before 9642479a (convert: fix leaking
config strings, 2024-08-01) straightened out the ownership rules of
the value obtained from git_config_string().

The fix makes sense.  Will queue.  Thanks.
