[PATCH] D25587: Introduce llvm FormatVariadic

[Pavel Labath via llvm-commits]

labath added a comment.

Will it be possible for the custom part of the format specifier to contain `:`? So we can specify custom formatting for time points with something like `formatv("{0:YYYY-MM-DD hh:mm:ss}", system_clock::now());`. (It does not seem that it will be a problem at a first glance, but I thought I'd check).
