Which is normally "nothing" on POSIX, since the shell does it for
you. Or, if you're talking about what the shell does for you, while I
suppose there is a basic globbing defined by POSIX, but bash and zsh
go well beyond that, and they behave somewhat differently in corner
If the program is going to invoke a globbing function specifically, I
suppose it makes sense to default to the same behavior as on the
current platform, but it's not obvious that that's what the user
wants. I use bash on Windows; why settle for cmd.exe if you want the
power of the command line? It could even cause problems (is there a
reliable way to determine what the shell is, let alone whether it
implements globbing or not, on Windows?)

But there *is* a RightThang for paths; the OS decides. Globbing is a
user preference thing.
