[PATCH v3] rebase -X: do not clobber strategy

[Martin von Zweigbergk <martin.von.zweigbergk@gmail.com>]

If any strategy options are passed to -X, the strategy will always be
set to 'recursive'. According to the documentation, it should default to
'recursive' if it is not set, but it should be possible to set it to
other values.
