It should be sufficient to squash something like this in. Use the
configured value, if available, to initialize the existing "mailmap"
variable, which is in turn updated from the command line option with
either --use-mailmap or --no-use-mailmap. What is left in "mailmap"
after the command line parsing returns is what the user told us to
use.
Thanks.
