This line wants to say "Stefan Xenos <sxenos@google.com>" to match
S-o-b below (I am assuming that you are following your employer's
open source recommendation to contribute under your corp address).

Perhaps you would want user.email set to the corp address?  I am
taking the above as an indication that the commits we are seeing
here have been made under your @gmail.com address and that is why
git-send-email is adding the in-body header.

Style: blank between decl and first stmt, perhaps?

No need for {} around a single statement.

Likewise.

Style: no SP between redirection operator and its target, i.e.

	echo 1 >expect &&

Likewise.

	echoid "" 88 44 aa 55 >>expect &&
