gitk shows local uncommit changes after touch file + reload

Hi,

Not sure if this has already been reported, but I observe this odd behaviour in gitk from master:

git status gitk # everything looks good touch <file-under-version-control> gitk # gitk shows "local uncomitted changes" on the file I touched git status gitk # gitk is back to normal again, showing no local uncommitted changes

The issue has been discussed on stackoverflow here: https://stackoverflow.com/questions/49990403/after-tar-untar-of-git-repo-gitk-shows-local-uncommitted-changes-not-checked

Any chance gitk could be changed to so that it doesn't display the "local uncommitted changes" blob in this case ?
