build git from source 🚀
add a simple global .gitignore
add some git aliases
build basic but latest vim
only try to install vim-fugitive once

No plugin is _that_ good.
less crazy way of making .vim subdirectories
bash-complete essentially everything
remove reference to rbenv-vars
force cloning of *env tools but not their plugins

force=no seems to save time and bandwidth when the repositories haven't
changed.  This works for plugins just fine, but the git module seems to
think the .nodenv and .rbenv directories get dirty and won't mess with
them.
add gs and gd aliases
lengthen vimrc a bit
don't specify patch level for ruby versions

When a patch level is not specified, ruby-build will get the latest one,
which is probably what I want.  Someday.
remove system ruby 😈
set Y to yank-to-eol in vim

d is delete, D is delete-to-eol. c is change, C is change-to-eol, y is
yank, Y is...yank entire line?!  That's what yy is for!
stop doing upgrade-dist for now
add testem to default node modules
