;;; Commentary:
;; This package provides a globalized minor mode that replaces the
;; major mode name in your mode-line and places like Ibuffer with an
;; icon. Currently the following programming modes are supported,
;; among others:
;;
;; - C
;; - C++
;; - C#
;; - CSS
;; - Coffee
;; - Dart
;; - Emacs-Lisp
;; - HTML
;; - Haml
;; - JavaScript
;; - Lisp
;; - Lua
;; - nXML
;; - PHP
;; - Python
;; - React
;; - Ruby
;; - Rust
;; - Sass/Scss
;; - Scheme
;; - Shell-script
;; - Slim
;; - Snippet
;; - Web
;; - Yaml
;;
;; To enable this minor mode add the following line to your init file:
;;
;; (mode-icons-mode)
;;
;; As of version 0.3.0 this project includes some icons which can use icon
;; fonts instead of images. These fonts are:
;;
;; - Font Awesome, found at URL `http://fontawesome.io/'.
;; - GitHub Octicons, found at URL `https://octicons.github.com/'.
;; - Font Mfizz, found at URL `http://fizzed.com/oss/font-mfizz'.
;; - IcoMoon, found at URL `https://icomoon.io/#icons-icomoon'.

This macro restores the buffer state under the assumption that no
significant modification has been made in BODY. A change is
considered significant if it affects the buffer text in any way
that isn't completely restored again. Changes in text properties
like `face' or `syntax-table' are considered insignificant. This
macro allows text properties to be changed, even in a read-only
buffer.
This macro should be placed around all calculations which set
\"insignificant\" text properties in a buffer, even when the buffer is
known to be writeable. That way, these text properties remain set
even if the user undoes the command which set them.
This macro should ALWAYS be placed around \"temporary\" internal buffer
changes \(like adding a newline to calculate a text-property then
deleting it again\), so that the user never sees them on his
`buffer-undo-list'.
However, any user-visible changes to the buffer \(like auto-newlines\)
must not be within a `ergoemacs-save-buffer-state', since the user then
wouldn't be able to undo them.
The return value is the value of the last form in BODY.
This was stole/modified from `c-save-buffer-state'"
