Subject: [PATCH] extract-word: don't rely on C's downgrade-to-bool feature for
5d016e
 chars
5d016e
5d016e
The `quote` char variable ectually contains a character, not a pointer
5d016e
or boolean. hence do an explicit comparison rather than rely on C's
5d016e
downgrade to bool feature, as per our coding style.
