This works because the current version of grep (2.6.3-1) doesn't treat
its input as binary by default, but strips the carriage returns from
the output of net localgroup. So grep -iq "^${username}$" matches, but
grep --binary -iq "^${username}$" doesn't.

No, od -c shows the \r\n endings in the output of net localgroup.
