This points out another bug/inconsistency, this time with '('.  It
looks like '(' and ')' are inconsistent in their handling of sentences
with only a single space.

Given the same text, if you position the cursor at EOF (or inside
the second sentence) and use '(' it will go to the start of the
second sentence, even though there is only a single space after the
period.  Historic vi goes all the way to the "Lorem", which is the
documented behavior.
