WezTerm is a GPU-accelerated cross-platform terminal emulator written in Rust

From my experience, the colon separator for 256/rgb attributes is a fairly recent clarification to the spec. I think that's the way it was always supposed to be. But when I was initially writing the 256 color support for the Windows Console about 6 years ago, `TERM=xterm-256color` still emitted colors with just the semicolons as a separator.

The colons are more correct, but the semicolons are seemingly more broadly supported.

Part of the problem is probably that termcap uses : as a separator between capabilities. There is \C for colon, but there are implementations that don't support it. If nothing else I know the termcap[info] command in screen doesn't.

That doesn't stop terminals from supporting it of course, just from saying they do.

I don't recall where I saw it, but my understanding was that : was in the original spec but one of the early implementors (Konsole?) misread it and used ; and that erroneous form is what took off, and here we are today.

I'm guessing it may have been one or both of these `xterm`-related documents:
