For GNU cat, `-e` is equivalent to `-eV`. `e` prints the non-printable
characters and `v` puts `$` on the end of the line.
```
-e equivalent to -vE
<...>
-E, --show-ends
display $ at end of each line
-v, --show-nonprinting
use ^ and M- notation, except for LFD and TAB
```
For Mac (https://www.unix.com/man-page/osx/1/cat/) and BSD
(https://man.freebsd.org/cgi/man.cgi?cat(1)), `-e` is `-v` with the addition of
adding `$` on the end. There's no separate `-E` option.
It has been `cat -e` since the test was added in
https://github.com/llvm/llvm-project/commit/de019b88dd5804ec996fe8c12cddcc6feb13afa1
/ https://reviews.llvm.org/D81058.
Using `-v` works fine because the test does not look for the `$` on the end of
the line, just the (usually) non-printable colour characters.
So I don't think there is any problem with landing this, once you add the
option explanation to the PR description.
