Hmm. Are these three supposed to be orthogonal?
The semantics of those 3 flags are not orthogonal, no. Their relationship
amongst each other is one of transitive implication:
-w implies the other two
-b implies --ignore-space-at-eol
--ignore-space-at-eol implies only itself
Therefore, it is never *necessary* to specify more than one of these flags on
the command line. However, it is not hard to imagine scenarios where software
wrappers around git (e.g. GUIs, etc), generate command lines with more than one
of these flags. I thought about it, and it seems unreasonable to make it an
error to specify more than one, since a new user might not immediately grasp the
way they imply each other. I think Git could and should treat it as a legal
case. I contacted Dscho about fixing it, but he is busy so I will submit a fix
patch myself.
