Grate the frozen butter into the flour next time, it blends in way easier and keeps everything cold.

Actually I think you might be slightly off on what happened there. Trailing spaces aren't usually the kind of thing that breaks a parser unless it's specifically checking for exact matches or stripping whitespace in a weird way. More likely it was a newline or carriage return character that was invisible to you in the terminal. When you cat a file it shows spaces just fine actually but carriage returns get hidden. I'd double check by running cat -A on that file to see all the hidden characters just to be sure. I spent four hours once on a bug that turned out to be a stray tab character that looked exactly like eight regular spaces in my editor.
