Anybody need a hairless yak?
Every time i tried to use a longer option in #ag (The Silver Searcher) in Cygwin, it complained about _split_longopt.
So i spent like half an hour hunting down exactly which file defined the #bash completion for ag on cygwin.
It is /etc/bash_completion.d/ag.bashcomp.sh
For some reason bash completion are split between that directory and /usr/share/bash-completion/completions/.
Putting them in one directory would have been too easy.
