Default to not wrapping long function names etc that are too big for the window.
If wrap=true is set, use some sane linebreak/breakindent/showbreak
options to wrap with an indent at the current indent level of the UI
tree, instead of just wrapping back to the far left side of the window.
For now we have some stuff out of that module to prevent infinite
require loops (set_keymaps/clear_state), but once state goes into its
own module as well then we can work it all into view.lua
