Very true! Often regression tests seem pretty wrong or at least dubious,
and if one looks at the .sgf-file, one realizes that the original problem
has long disappeared. This would make updating of regression tests much
smoother.

What about:

loadsgf  games/trevor/auto/c18.sgf 103
=
undo
=L1

That would avoid introducing another command or more .sgf-related global
variables, but it would change an existing GTP v2 command. Hmm.
