(Seen in 1.7.12.3)
When launching git gui in a repo where there are 1. lots of (>5000) stashed changes (to do a tree move), and 2. many non-packed files, git gui throws 2 alert dialogs: one saying that it will only show 5000 changed files and ignore the others, which very quickly hidden by the offer to repack. If I decline repacking, then both dialogs are discarded, and the first one, which is quite critical, may not have been seen at all by the user.
