* findref: Support file matching options: --include, --exclude, --want-get, --want-drop, --largerthan, --smallerthan, --accessedwithin * Commands supporting --branch now apply file matching options --include, --exclude, --want-get, --want-drop to filenames from the branch. Previously, combining --branch with those would fail to match anything. * add, import, findref: Support --time-limit. This commit was sponsored by Jake Vosloo on Patreon.
