completions/git: Shorten alias descriptions

Browse source 
I have an alias called "lg" for

log --color --graph --pretty=format:\'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)<%an>%Creset\' --abbrev-commit --first-parent

Having that in my completions ensures that git commands essentially
always use one column at most. That's not great, so we now shorten it
to 35 chars (plus an annoying 2 for ".." because I can't be bothered
to check for unicode support - an argument for a "string ellipsize", I guess?)
