Remove ParEdit entry from `el-get-sources`.
Install Emacs’s Smartparens version "1.5".

I grabbed the `smartparens.rcp` file from the `master` branch of
`el-get`.
Enable smartparens-mode globally by default.
Revert "Enable smartparens-mode globally...".

Apparently that doesn't work. Hm.
Fix Smotitah startup error.
Switch to MELPA version of Smartparens.

Because the latest "released" version (i.e., the version on Marmalade,
1.5) doesn't have `smartparens-strict-mode` on it.
Start out with Smartparens’s default config.
Enable basic ParEdit functionality.
fixup! Enable basic ParEdit functionality.
Merge branch 'ParEdit→Smartparens'
Add my home `bin` directory to the `PATH`.

(in both `fish` and in `bash`)

Certain apps install helper/wrapper scripts there, like Sourcetree,
TextMate, Chocolat, RubyMine, etc.

(also, I intentionally switched the quoting style in the `.shrc` change)
"Emacs, overwrite selected text if I start typing."

It used to be *appending* where the "point" was regardless of whether
I had any text selected.

Instead of ~/.rbenv, use Homebrew’s directories.
Prepend rbenv’s shims to the $PATH.

This effectively puts `rbenv` in control of which Ruby
binaries are visible.
Uniformly rearrange the `el-get-sources` plists.

The internal key/value orderings got moved around because either
El-Get or "Easy Customization" (or both) determine some of the
semantics of `el-get-sources` from the K/V orderings. With
`:checkout` listed _second_, it just displays as a custom build-tag
instead of being listed next to "Checkout this `git' revision: ".
