stay-local-p is used to determine not whether to use some optimizations but
whether to use some heuristic rather than the real thing.

I.e. (vc-stay-local-p FILE) should be non-nil if FILE's repository is on
a far away server, i.e. if querying the status of FILE will take a long
time.  This is the used to avoid querying the server when it's not
absolutely needed, and also triggers the use of async operations where
supported.

So I think (a) is right, because if any of the files are on a distant
repository, the resulting command will take a long time, even if all the
other files's repositories are nearby.
