User Guide: Improve intro to GUI section

[msiism]

The second sentence in the first paragraph of the GUI section in Haiku's User Guide (​https://www.haiku-os.org/docs/userguide/en/gui.html) reads:

Unlike Unix-based operating systems, there's no separate window manager and booting just into a command line shell is not possible.

I suggest changing that into:

Unlike other Unix-like operating systems, there is no separate window manager and booting just into a command-line shell is not possible.

Reasons:

That beloved window manager overkill is not a specialty of Unix-based systems (take macOS, for example). Rather, it is typically found on Unix-like systems such as Linux and BSD.

Also, the changed version of the sentence implies that Haiku is indeed a Unix-like operating system whereas the original version kind of implied the opposite.

I'm still not entirely happy with saying "there is no separate window manager" because this is actually about the whole graphical environment not being separate, not just the window manager.

Made the change, will be included with the next export from the user guide site.

I was always under the impression Haiku wasn't Unix-like. Maybe I just confuse that with the old saying, "Haiku is not Linux". :) Anyway, I'm not really interested in that discussion as it probably will boil down to what exact definitions different people want to apply.

Maybe. OTOH, I expect most people reading the User Guide couldn't care less. Should they come from Linux, they may have heard about using different window managers, so they may appreciate the different situation in Haiku. At least in the forums, the question of using a different WM crops up from time to time.
