Remove trailing newline when STDOUT is piped

[spenserblack]

For example, I can use xcolor | xclip -selection clipboard to copy the color to the clipboard. Whenever I do this, it's copied with the trailing newline. So when I paste it into code, it's slightly annoying because I have to manually remove the newline. For example, if I was going to paste a selected color into a Markdown comment (#347d39) I wouldn't want the trailing newline.

Oh, gosh, I've been using this tool for a long time without knowing that xcolor takes the -s clipboard option, so I never needed to pipe to xclip 🤦 😅 Just found out now from digging into the code.

Still, this could be handy just for compatibility with other use-cases that might involve piping.
