I can't reproduce this bug anymore (you can stop reading here).  I'll
explain what I thought the bug was for posterity.

With sendmail-program set to /usr/bin/msmtp.  Without the patch below,
msmtp finds its config file in the default location ~/.msmtprc .  It is
possible specify a different config file on the command line using the
-C option.  However, using this:

(setq message-sendmail-extra-arguments '("-C"
       "/home/myles/.config/msmtp/msmtprc"))

did not result in msmtp finding its config file.  The doc for
message-sendmail-extra-arguments says "Additional arguments to
`sendmail-program'".  The 'bug' was that the extra argument should be
applied but it is not.

After applying the patch below, the config file is found in the
non-default location.  The 'bug' is fixed because the extra argument is
applied.

I don't know why the patch works or much about elisp (I copied from
elsewhere in the source).

While debugging, message-sendmail-extra-arguments seemed to be something
other than a string, the patch below seamed to cause it to be string
consistently.
