Yes I have tried it.  An empty string causes the SMTP auth Perl module
to choke.  It expects a non-empty username and exits with an error.

On my system I have patched git-send-email to perform this check:

if (defined $smtp_authuser and length $smtp_authuser) {

This works but feels like a hack.  I think unset override could be
useful for any git config option, not just sendemail.smtpuser.

I'm not familiar with git internals; do you have other suggestions for
solving this issue?
