* Remove unnecessary `uniq`
* Look for tags in tmp/tags or .git/tags
* Send errors to /dev/null if the file(s) do not exist
See http://tbaggery.com/2011/08/08/effortless-ctags-with-git.html for an
explanation behind the reasoning for .git/tags.
Project should be moving over to spring, as this is the 'blessed'
approach and is part of suspenders. Leaving these functions around adds
yet another layer of indirection to consider when trying to run these
commands:
* function wrapper
* binstub
* rbenv shim
* actual binary
* Fixes an issue where tab completing specs that start with the same
words(s) makes tab completion freak out and stop working.
* The con is that we'll see "_spec.rb" in the output, like:
```zsh
$ rspec spec/models/
models/calendar_spec.rb
models/event_closer_spec.rb
...
```
With arguments, g acts like git.
Without arguments, it runs `git status`.
* Source functions/* after loading ZSH completion so `compdef` is available to g
alias

* ag is faster than ack
* ag searches all files by default (but still ignores gitignored files). This
removes the need for ack's `--type-add=` options.
* The command is 33% shorter than ack!
* Use a regular alias to make `s` short for `rspec`
* Use an `rspec` shell function to route to zeus when appropriate
* Removes confusion from `s` working differently than `rspec`
* Removes need to use a special alias to get zeus working
