Wine/Proton logging behaviour

What does Proton (and Wine, while we're on the subject) log by default if you set PROTON_LOG=1 but do not set WINEDEBUG? I've been able to find information about Wine debug (logging) channels on the official Wine wiki, but nothing about the default behaviour. - https://gitlab.winehq.org/wine/wine/-/wikis/Wine-User's-Guide#winedebug-channels - https://gitlab.winehq.org/wine/wine/-/wikis/Debug-Channels

https://github.com/ValveSoftware/Proton/blob/f1933d3f9cde5b9fdd357f53cf509f7fee362ade/proton#L1466 Note that Heroic sets WINEDEBUG=+timestamp if you just set PROTON_LOG=1 (without setting WINEDEBUG yourself). I've made this change since it leads to significantly smaller log files; you usually don't need all the extra channels
