So here it is capitalized email address (BUGS@), but at the expect file
it's still lower cased. I think this is a bug.
Junio was trying to fix it in 543f99173c2d2f648d8f846e24875150f7de03d3
(origin/jc/mailmap-case-insensitivity)
So I think we need another yet test case there:
commited:
    Internal Guy <BUGS@Company.xx>
    Internal Guy <bugs@company.xy>

Having just one entry in the mailmap
    Internal Guy <BUGS@Company.xx> <bugs@Company.xy>

should still work with the "shortlog -e"
