We codify the following different heads (in addition to the main "HEAD", which points to the current branch, of course): - FETCH_HEAD Populated by "git fetch" - ORIG_HEAD The old HEAD before a "git pull/resolve" (successful or not) - LAST_MERGE The HEAD we're currently merging in "git pull/resolve" - MERGE_HEAD The previous head of a unresolved "git pull", which gets committed by a "git commit" after manually resolving the result We used to have "MERGE_HEAD" be populated directly by the fetch, and we removed ORIG_HEAD and LAST_MERGE too aggressively.
