Although Git interally has the facility to differentiate between porcelain and plubmbing commands and appropriately print errors, several shell scripts invoke plubming commands triggering cryptic plumbing errors to be displayed on a porcelain interface. This patch replaces the "needs update" message in git-pull and git-rebase, when `git update-index` is run, with a more friendly message.
