[Emacs 24.4] Improve fullscreen support

[syl20bnr]

In Emacs 24.4 there are 2 functions to toggle the frame fullscreen:

• toggle-frame-fullscreen removes window manager decoration (no title bar, no taskbar on windows)
• toggle-frame-maximized respects window manager decoration (regular maximize)

On windows, it is not natural to hide the decorations.

2 possibilities for the behavior of dotspacemas-fullscreen-at-startup:

• dependending on the window system we dispatch to toggle-frame-fullscreen or toggle-frame-maximized (say the latter for Windows only)
• specific symbol value for the variable:
  • nil, with-decoration, without-decoration
  • nil, fullscreen, maximized

Need your feedback.

Although I like full screen, I only like it as default in applications like games. With text editors and terminals I like them to maximise and I will full screen them if required. On Mac the full screen is stupid too, it has some weird animation that I can't turn off so I only maximise. But on Linux it works find so I sometimes full screen.

I think you should just maximise and let users full screen easily, maybe with SPC w f or SPC w t f (WTF :D). That gives the most functionality without assuming what some users want and changing things depending on the platform.

+1 for maximized sane default

I also prefer maximized over no-chrome fullscreen.
