Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).
No functional changes.
Rather than enabling/disabling cursor highlighting by going into mouse
settings, you can now instead toggle it any time with Super+H. Mouse
settings now is only for customising the look of the highlighting.
