[FIX][BUG] TextMorph 'text color...' interface 'cancel' button doesn't work ( [er][et] with addition to revert extent, this time with changeset )

[ned at squeakland.org]

Missed sending the prior changeset because of a BFAV problem.
This is the same as the prior, but also reverts extent if you change the
wrap flag and then cancel.
