In a regular expression, ^ matches the beginning of the string, and $ matches the end; I'm referring to those as anchors. So ^xyz$ matches only "xyz", but the pattern xyz matches (for example) abcxyzdef. IS_MATCH is a little confusing in this regard, because it has some options for automatically anchoring the search, and those options are a little different in the trunk than in stable. But if you want an anchored search, it never hurts to make it explicit with ^ and/or $.
