This supports now curly, double, dashed, and dotted underline styles
where trhe terminal supports it. This works well on Windows Terminal,
reasonably on iTerm2, Alacritty, Kitty, and probably others.
The wasm mode terminal includes support for this, dependent on the browser
capabilities.
The macOS Terminal just changes the background color. Legacy Windows
console does nothing.
We will try to provide a regular underscore as a fallback. A new style.go
demo is included to see some style combinations.
Previously we had lost StrikeThrough, and this fixes a few other
discrepancies. This was generated on Ubuntu Noble (24.04), after
installing the following packages: ncurses-term kitty-terminfo
This fix is not perfect, in that it will not fix every terminal that has
automargin support, but it fixes the *vast* majority of them by eliminating
the hacky workaround for the automargin - essentially using the rmam capability
to disable automatic wrapping at the margin.
This adds optional MouseFlags that can be used to adjust what is
tracked for mouse reporting (leaving the other modes to be handled
by the terminal.) This should work on all XTerm style terminals,
but on Windows we have no way to be selective here.
