RFD: fast-import is picky with author names (and maybe it should - but how much so?)

It seems that our fast-import is super picky with regards to author names. I've encountered author names like

Foo Bar<foo.bar@dev.null> Foo Bar <foo.bar@dev.null foo.bar@dev.null

in the self-hosting repo of some other dvcs, and the question is how to translate them faithfully into a git author name. In general, we try to do

fullotherdvcsname <none@none>

if the other system's entry does not parse as a git author name, but fast-import does not accept either of

Foo Bar<foo.bar@dev.null> <none@none> "Foo Bar<foo.bar@dev.null>" <none@none>

because of the way it parses for <>. While the above could be easily turned into

Foo Bar <foo.bar@dev.null>

it would not be a faithful representation of the original commit in the other dvcs.

So the question is:

- How should we represent botched author entries faithfully?

As a cororollary, fast-import may need to change or not.

P.S.: Yes, dvcs=hg, and the "earlier" remote-hg helper chokes on these. garbage in crash out :(
