This patch adds another variation to hoshi_keima.sgf.  I don't see this
line in Ishida, so this is really just my own work here (that is, someone
stronger should make sure it looks ok).

This produces three PASSes at nando:210, nando:211, and nando:212.
nando:210 should be considered basically accidental; the other two are
properly solved.

I haven't run the rest of the regression tests, but I don't anticipate any
