Why 2 spaces after commas here?

> Well, it is sorted by `core_type + number` in all other places in LLVM codebase (including error messages). GCC also sorts them as [[ https://github.com/gcc-mirror/gcc/blob/master/gcc/config/riscv/riscv-cores.def | E-S-U ]]. As well as [[ https://www.sifive.com/risc-v-core-ip | sifive.com ]]
Ok. I was basing that request on our internal codebase where we have them sorted the other way. But it doesn't matter a lot to me.
