Remarks

while this diagnostics can be crucial for finding bugs, we avoid including format-string.hpp, since lib::Variant is used pervasively as part of lib::diff::GenNode. Especially in development builds, we observed a tangible leverage on executable size. Thus we implement the protection against follow-up exceptions explicitly here.
