#2 bothers me because it's a special case of #3 but with a different
interpretation from #3.

How about if the default skeleton path is the directory the grammar
was found in, followed by the standard Bison skeleton directory?
That's similar to how '#include "foo.h"' works in C.  A downside of
this approach is that one cannot refer to the standard Bison skeleton
file if there's a file with the same name in the working directory,
but the usual solution for this (#include_next in GCC) is even better
than #2 since it works even in include files and even when the include
path length is longer than 1.
