Avoid mix char with bool type in comparisons

Hi,

GIN Indexes:

Defines a type char GinTernaryValue with 3 values:

#define GIN_FALSE 0 /* item is not present / does not match */
#define GIN_TRUE 1 /* item is present / matches */
#define GIN_MAYBE 2 /* don't know if item is present / don't know
* if matches */

So, any use of this GinTernaryValue are:

1. if (key->entryRes[j]) be FALSE if GIN_FALSE

2. if (key->entryRes[j]) be TRUE if GIN_TRUE

3. if (key->entryRes[j]) be TRUE if GIN_MAYBE

So gin matchs can fail with GYN_MAYBE or I lost something?
