We do want to learn what prefix the user wants to use when they
start their command line with "git svn --prefix". Stopping the
command line right there and expecting it to default to whatever
built-in prefix is simply strange; the user could have omitted that
"--prefix" that lacks the argument. If the user did want us to use
the default by passing an empty string as its argument, both forms,
i.e. "--prefix ''" and "--prefix=''", ought to be usable, but if
older Getopt::Long() does not allow the latter form, at least the
former is the right way for the user to tell us that.
So I think your fix (workaround for a bug in older Getopt::Long) in
the patch is the right one. Johan may want to help me by pointing
out if I am missing something.
Thanks.
