I always wonder how many people who say that have actually *tried*
Emacs' editor.

Actually, I think the issue is just that Emacs' ANSI color parsing code
is effectively O(n^2); when I really, really need colored output I run
the command in a separate window (with B&W output) and switch major

Emacs' terminal is also lacking all the modern conveniences, like
addressable cursors and builtin line-editing designed for 1970s printing
terminals and practically no searching capabilities.  Alternatively, you
could say it's incompatible with modern Unix's biggest mistakes and
worst legacy issues.

Of course.  It sucks the least of any solution I've tried.  Barely.

Yi has a terminal?  Maybe I should try it again.
