examples/cgit-commit-filter: improve quoted text handling

With an example such as:

	something before "quoted phrase" something after

The Xapian will now see:

	[ "something before", "quoted phrase", "something after" ]

whereas before it would see:

	[ "something before", "quoted", "phrase", "something after" ]

which should improve search results accuracy when looking
up commits by commit title (subject).
