You are welcome, and thanks for your efforts here. That is a better title I'd guess.
The problem looks to be important as the code section is likely passing a longer string to snprintf than it indicates with the character count. Adding the additional "-" guarantees that you will be one longer than expected from what I can see.
I'd think that you'd need to track current new token chars on top of current past line length chars as well as total buffer length. This approach looks to not check return from snprintf, not ideal, and just "Adding" the "-" says using sizeof the current token, which gets bumped by one, and the length means Gcc is right to complain.
