":help -b" gives a little more detail but I'm not sure whether I've
found a bug.

When when opened with

vi -u testvimrc testfile

it has the following settings

:set modeline? ts? et? sw? bin? ff?
modeline
tabstop=2
expandtab
shiftwidth=2
nobinary
fileformat=dos

And when opened with

vi -u testvimrc -b testfile

it has the following settings

:set modeline? ts? et? sw? bin?
modeline
tabstop=2
expandtab
shiftwidth=2
binary
fileformat=unix

Based on the ":help -b", I would have expected that 'noexpandtab' and
'nomodeline' would appear in that output, and that my ts/sw would be
4 (set in the vimrc) rather than the ts/sw from the file's modeline
contents. It does correctly prevent munging of CR/LF by setting
ff=unix and 'binary'.
