+ * Fix an aggregate plugin expiry bug. Over time, it's possible for the same
+ page name to be expired and reused for several distinct guids. When this
+ happened, the expiry code counted each past guid that had used that page
+ name as a currently existing page, and thus expired too many pages.
+ * Avoid a race in the git rcs_commit function, by not assuming HEAD will
+ stay the same for the duration of the function.
+ * Avoid using commands like git-diff and instead use "git diff".
+ In some configurations, only the main git command is in the path.
+ * Improve the RecentChanges display for git merges, by passing -c instead
+ of -m to git-log, and by skipping display of commits that change no
+ pages.
+ * Don't truncate git commit messages to the first line in RecentChanges,
+ show the full message.
