Goes all the way back to the days of teletypwriters and occasional dumb serial
terminals that only knew uppercase.
If the login name came thru to getty all uppercase, than for the
session, uppercase was mapped to lowercase. This allowed a person to
move around logging in from hi-tech upper/lower case terminals and stupid
uppercase only terminals as the same user. IBM terminals were a big
offender back then. Hollerith to EBCDIC.
This probably ought to retire, but it's so implicit in so much legacy code.
