Unless the tweaks still aren't quite right and are stripping the leading
whitespace from the continued headers. ;-)

nmh can't handle that; it's invalid input and not generally resolvable
as to what was meant. The original
X-Mailer: Foo, Version: 3.14
could be corrupted to
X-Mailer: Foo,
Version: 3.14
and that's perfectly valid input of two headers.

Just to note they don't have to have a capital letter at the start.
I think this is a fairly unusual problem that needs an ad hoc solution
each time to cope with the peculiarities of each case.
Cheers, Ralph.
