This eliminates the previous performance cost by making 'got log -d' and tog diff view compute the diffstat while building the diff in a temp file like we do with 'got diff -d'. Also, keep the current 'got log -d' UI as per stsp's suggestion. ok stsp@

Accept flag parameter to optionally specify which pointers to free. This saves callers looping through the list to free pointers. ok + fix stsp@

Like got log -d, add the switch to 'got diff' to display a diffstat of changes; as per stsp's suggestion, we always include diff output with the diffstat. Disabled in gotwebd (for now :) Includes tweaks from op@ ok stsp@

This behaviour is already documented in got-worktree(5) but wasn't actually implemented. ok stsp@

My commit to reset committer info during rebase was too strict in some use cases. Even when simply forwarding a branch the rebase operation could now fail if GOT_AUTHOR is not set. To fix this, fall back on existing commiter information if no author is configured. And try to obtain author info from Git config in case GOT_AUTHOR is not set. Problems reported by Mikhail.

Now that the handling of including sys/queue.h is better, there's no need to remove those lines from the source. Copy the location of those original sys/queue.h lines from upstream at the same line number, so as to avoid any conflicts in the future.

Make the choice of diff algorithm configurable by diff API users. The got and gotweb programs keep using Patience diffs which are prettier than Myers. But tog should be as fast as possible since it is being used interactively. If performance of Patience diff gets improved later we can consider switching tog back over to it. ok tracey jamsek
