Consider conforming meson options to style recommendations
http://mesonbuild.com/Style-guide.html provides some guidelines on how to name meson options. In particular, it recommends dropping the "enable-" prefix from the options.
There's also no upstream guidance on hyphens versus underscores, but there's been an effort to standardize GNOME on using underscores.
For instance, the option
enable-gnome-desktop should probably be named
gnome_desktop. The option
enable-gspell should probably just be named
gspell. Changing this will irritate distributors, so better to do it sooner rather than later.
