I posted a prototype patch that does something like that. It's not exactly
trivial to support without duplicating a pile of code or being very specific
to one use-case. I might have over-complicated things though.

The downsides of handling this in kernel is that more strings are needed,
more code and it won't be of any use with reports from older kernels,
particularly distro kernels. There is scope for both having the script and
formatting it in-kernel.
