close_lock_file(): new function in the lockfile API
The lockfile API is a handy way to obtain a file that is cleaned up if you die(). But sometimes you would need this sequence to work: 1. hold_lock_file_for_update() to get a file descriptor for writing; 2. write the contents out, without being able to decide if the results should be committed or rolled back; 3. do something else that makes the decision --- and this "something else" needs the lockfile not to have an open file descriptor for writing (e.g. Windows do not want a open file to be renamed); 4. call commit_lock_file() or rollback_lock_file() as appropriately. This adds close_lock_file() you can call between step 2 and 3 in the above sequence. Signed-off-by: Junio C Hamano <gitster@pobox.com>
