Unfortunately we don't buffer the output so there's no way at exit time to go back and gather the output. The good news is that the planned changes should be directly helpful for the case you are encountering. We/I hope to add rebase support to get_source.sh so that local changes whether unpushed changesets, mq patches or uncommitted changes will be rebased to the new tip whenever you pull. > I guess I could go spelunking in the code to find out, but I’m too lazy and > prefer to bother someone else. :) Not a problem.
