gcc 8+ recognizes that space has not been left for the pid and that the return value of snprintf() isn't checked. Leave a little space for the pid to prevent `-Wformat-truncation`.
In recent gcc, -Wrestrict warns when an argument passed to a restrict-qualified parameter aliases with another argument.

Can you explain the semver label? It’s not obvious to me :) |

@addaleax see ---^ I'm OK with it not being semver-major, but if there was a process-name longer than 1000 chars, it would now be slightly truncated. How paranoid should we be? I'll let someone else decide.

I think this is okay, given that names of that length are very unlikely, and we mostly only use this for debugging purposes?
