Aliases to show or delete local branches that are not tracking remote anymore.

untracking_branches

# The commands will match "TD" pattern as branch name and "gone]" to check if branches are untracking.
# Note: Depending on language you have in your git client, "gone]" part may change to e.g. "desaparecido]".
# WARNING: In case the branch has "gone]" in some commit, prune command will also delete it.
# Same happens for unmerged branches, change it to "git branch -d" for a safer usage.
