Ugh. Can we please at least make this optional? Many modern MTAs handle
the current situation just fine by being much more strict in their
"From" matching (i.e., you would need something that really looks like a
valid "From" line to get a match), and do not do ">From" de-quoting at
all (mutt is such an example).
Some even take it a step farther and use Content-Length headers, though
I do not think that is a good idea here (we encourage people to munge
the contents while stored as an mbox).

This is the lossy "mboxo" conversion. A quoted From is now
indistinguishable from an original ">From". To be reversible, you need
to quote "s/^>*From />&/".
But of course, which conversion you want depends entirely on what you
are going to feed it to, and which mbox they are expecting. Which is why
it really should be configurable.
Your use case looks to be feeding it to send-email; I suspect you would
be better served by improving the 'From ' detection in send-email,
probably to something like:
/^From \S+ \w{3} \w{3} \d+ \d\d:\d\d:\d\d \d+/
though that may be too strict. It would probably make sense to steal one
from one of the many mbox-reading CPAN modules.
