Stray `^M` in a line ending

[mattip]

Not critical, but thought you might like to know. When looking at the diff to a previous version, I see a stray windows line ending ^M has crept into this line. It doesn't show up in the web view here, but vim displays it in diff view. https://github.com/intel/x86-simd-sort/blob/6a7a01da4b0dfde108aa626a2364c954e2c50fe1/src/xss-common-argsort.h#L632

@mattip thanks for reporting it, but I don't see it on my vim. what were you diff'ing when it showed up on your vimdiff?

On linux in the x86-simd-sort repo on latest main, do git diff df68479f2d6 src/xss-common-argsort.h.

Also, file sees the mixed line endings in src/xss-common-argsort.h:

$ file src/xss-common-argsort.h 
src/xss-common-argsort.h: C++ source, ASCII text, with CRLF line terminators
$ file src/xss-common-keyvaluesort.hpp 
src/xss-common-keyvaluesort.hpp: C++ source, ASCII text

chatGPT/Google AI says: The ^M character in a file represents a carriage return (CR) character. It is often seen when a text file created on a Windows or MS-DOS system is viewed or processed on a Unix-like system (such as Linux or macOS).

It is showing up on a lot of places actually. Been working on a patch on windows and that looks like it messed up some line endings :) thanks for reporting, will fix it :)
