[feature] color the file opened by vi

Some file types like log or txt does not have colorschema in vi.
Can Windterm support to color the text inside vi, such as number, ip,time, and keywords like error,warning,sys_debug, etc?
I see such useful feature in MobaXterm.

The issue names no files, tests, or entry points. Start by locating WindTerm's vi support and text-coloring paths, then define the supported text categories and verify that log or text files opened in vi display them with colors.
