Yeah, I am happy to take the credit/blame when somebody inevitably shows
a case where this does the wrong thing (I say inevitable because I
assume that is the fate of all regexes -- to one day be proven to miss a
corner case).
But surely you know that my commit messages are more verbose than that.

Here's what I would have written:

Subject: [PATCH] send-email: ignore trailing whitespace in mailrc alias file
The regex for parsing mailrc considers everything after the
second whitespace to be the email address, up to the end of
the line. We have to include whitespace there, because you
may have multiple space-separated addresses, each with their
own internal quoting.
But if there is trailing whitespace, we include that, too.
This confuses quotewords() when we try to split the
individual addresses, and we end up storing "undef" in our
alias list. Later parts of the code then access that,
generating perl warnings.
Let's tweak our regex to throw away any trailing whitespace
on each line.
