Hi,

Just noticed this when trying to use the new pum opacity feature.

set termguicolors seems to be required for opacity to work, but I don't see anything in the docs about this.

I will submit a PR if I get some time later, but please feel free to beat me to it :-)

Thanks — you're right that 'pumopt' in options.txt is missing the note (it's only under |popup-opacity| in popup.txt).

Related: #20095 added cterm-side blending as a side effect of another fix, so opacity now actually works without termguicolors. I've asked the maintainers there whether to officially drop the requirement and update the docs; if not, I'll send a small patch to mirror the note on the pumopt side.
