Addressing ^M (CRLF) line ending issues in user.js

[codayon]

I noticed that whenever I copied and pasted lines from user.js into my own configuration, an empty newline was being inserted after every line.

After investigating with git diff, I discovered the presence of ^M characters at the end of each line. This indicates that the files were saved with Windows-style line endings (CRLF), which can cause formatting issues when viewed or edited on Unix-like systems.

I have forked the repository and ran dos2unix to normalize the line endings to LF. Interestingly, only user.js and personal/user-overrides.js required conversion; the rest of the repository was already in Unix format.
