Missing Commentary on meow-esc.el in Docstring

Could we add a comment there?

I'm not sure what to put.

These codes are copied from evil to make esc work in terminal. :)

What should we write for the module docstring short explanation?

[DogLooksGood]

This module is used to patch the behavior of ESC key in terminal.

[jgarte]

Why was the patching required?

Just curious to understand the historical reason for it needing to exist.

It's because meta combos in the terminal send the exact same keycode as pressing ESC and then the key, which is why you can use ESC as meta in the terminal. This is problematic for evil and meow because esc is used while coding more frequently, if you press escape and then a key usually you don't want the meta combo. meow-esc-delay is the maximum time between ESC and the keypress that should be treated as a meta combo. If the time is longer than the delay, it's treated as pressing ESC and then the key separately
