If config parameter core.logAllRefUpdates is true or the log file already exists then append a line to ".git/logs/refs/<ref>" whenever git-update-ref <ref> is executed. Each log line contains the following information: oldsha1 <SP> newsha1 <SP> committer <LF> where committer is the current user, date, time and timezone in the standard GIT ident format. If the caller is unable to append to the log file then git-update-ref will fail without updating <ref>. An optional message may be included in the log line with the -m flag. Signed-off-by: Shawn O.
