git completion: use fancy ellipsis

Browse Source 
A recenty commit was loathe to assume the unicode ellipsis character
was safe so just used '..' instead. However I noticed we actually
already do use that character elsehwere in the completions.

So, just make both spots try to somewhat carefully use it.
We do this same `string match` check on LANG in fish_job_summary.fish
